Random application crash on Apple Silicon M1 (Qt 6.2.3)

KejPi

@sultan Yes, this is aligned with my observations. It happens very frequently when I boot my laptop and in time it is less frequent

KejPi

I have some observations to share. My app uses several libs installed by homebrew, specifically:

libmpg123
faad2
portaudio
librtlsdr that uses libusb to access RTL-SDR USB stick

If I build all these by myself and link my application with them it seems that it is no longer crashing. My suspicion would be libusb. I am trying to run the app with only librtlsdr + libusb from my own build and so far it seems to work or it is significantly less frequent. I need to test it more but it looks promising.

@sultan : Does your application use any of these libs, especially libusb?

EDIT: it just crashed :-( I will try with all libs from my local build that was working fine yesterday.
EDIT2: application does not crash when linked will above listed libs built locally on my Mac and not taken from Homebrew. I have tried to isolate the problem to single library with no success so far. I will continue my investigations and try to find more information.

sultan

@KejPi My application uses libaravis from homebrew, which depends on libusb (also from homebrew).

KejPi

@sultan Could you please try to build both libs locally and link your application with them? Since I did that for all my libs, I do not have problems with crashes but it seems that all have to be built locally - I do not understand it at all :-(

sultan

@KejPi I’ll try that out when I get some time (it’s a side project of mine). I could also diff the resulting library binaries if indeed that prevents the crashes.

I'm seeing this exact crash with all libraries locally built, none of the libraries listed here and built on Gtk (yes, I'm in the wrong forum :). So I think this is likely a MacOS bug, but I don't know for sure.

I'm still having the same issue, same crash stack trace, on Mac OS 12.6.3 with Qt 6.4.2. I haven't yet gotten to trace my way to the root cause, though it looks like this will be a PITA to debug.

SGaist

Do you have the same issue if you use a Qt version coming from the online installer rather that brew ?

DerReisende

@sultan have you tried to completely remove homebrew from your system and then reinstall only the needed library for your app? I have seen a CERN ROOT framework crash that was related to a "wrong" library being somewhere in LD_LIBRARY_PATH which was causing the crashes similar to these described here.

sultan

@SGaist I am using the Qt 6.4.2 from the online official installer for Mac

sultan

@DerReisende I think you're on the right track here. When launching the application from Qt Creator, it consistently crashes (after some random delay) when the computer has been rebooted recently. When launching the application from command line (going into the .app bundle's Contents/MacOS directory and invoking the executable from there), it never crashes. So there is definitely some library mismatch happening when launching through Qt creator that is avoided when launching from the command line.

For reference, when launching from the command line (where it doesn't crash), PATH=opt/homebrew/bin:/opt/homebrew/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin and LD_LIBRARY_PATH is not set. When launching from Qt Creator (where it crashes), PATH=/Users/sultan/Qt/6.4.2/macos/bin:/usr/bin:/bin:/usr/sbin:/sbin, QTDIR=/Users/sultan/Qt/6.4.2/macos, and LD_LIBRARY_PATH is again not set.

@sultan said in Random application crash on Apple Silicon M1 (Qt 6.2.3):

It seems just launching the application from Finder (by clicking on the .app bundle) also works properly with no crash - at least I have not been able to reproduce any crashes that way, whereas I've been able to reproduce this crash almost a dozen times today when launching the app via Qt Creator (soon after a reboot).

jcelerier

Same crash here, happened consistently as soon as I did a filesystem save operation in my soft: i could fix it by unchecking "Add build library search path to DYLD_LIBRARY_PATH and DYLD_FRAMEORK_PATH" in Qt Creator's Project > Run tab.

@sultan note that LD_LIBRARY_PATH is for ELF platforms, MacOS uses DYLD_LIBRARY_PATH

Trying on a terminal, I can see that just adding /opt/homebrew/lib to DYLD_LIBRARY_PATH is sufficient to trigger the crash.

jcelerier

Continuing my investigations:
here are 2 runs of my app, one with DYLD_LIBRARY_PATH=/opt/homebrew/lib and one without, using DYLD_PRINT_LIBRARIES=1 to see the libs that macOS loads:

the one that is ok: https://paste.ofcode.org/YgwDFyPekpfvAQXbLp5wYk

the one that crashes: https://paste.ofcode.org/et4HZsbsAGkLPMV2QcPd2w

the interesting thing: if I diff them, the only difference is that the one that crashes DOES NOT load the following libraries ; everything else is exactly the same:

SGaist

@jcelerier it seems a bit more convoluted than that.

For example, both run have lzma loaded but from two different locations. I am wondering whether there is some incompatibility between loaded libraries (not necessarily lzma maybe others as well).

jcelerier

still happening as of Qt 6.7.1 :/

SGaist

Do you still have similar dependencies loaded from different places ?

sarkara

While investigating a similar crash from a different (non-QT) app, I narrowed it down to libpng from Homebrew. I opened a discussion on https://github.com/orgs/Homebrew/discussions/5420.
