QtCreator crashes

batguano

QtCreator crashes on me, at least 4 or 5 times a day. Is anyone else having this problem?

There's no discernible pattern to the crash; it sometimes happens when it's just sitting there & I'm staring at my code.

My system is a Mac 10.9.4, using Qt 5.3.1 and QtCreator 3.2.1 (although the same crash happened has happened under 3.1.2). I've clean-installed Qt a couple times (when upgrading) and still have the crashes.

Here's the top of a typical crash log (I can send more if that's helpful):

Sometimes the the "Exception codes" line looks like this:

Exception Codes: EXC_I386_GPFLT

Any advice appreciated!

Hi and welcome to devnet,

When you built Qt Creator, was it with a self-built Qt ?

batguano

I downloaded the binary of Qt Creator, rather than building from source.

batguano

I've submitted a bug report, QTCREATORBUG-12964

SGaist

Ok, good, thanks for sharing the link

hskoglund

Hi, I see in your crash log QTimerInfoList::activateTimers(), and there are many bug reports filed for that function, like "this one":https://bugreports.qt-project.org/browse/QTCREATORBUG-11262

But the good news is, now there seems to be a solution, perhaps it's applicable for you also: launch QtCreator and select About Plugins... and check if you have the UpdateInfo plugin enabled. If so disable it. (This is from the bug report link above).

batguano

Thanks, hskoglund! The UpdateInfo plugin was enabled, so I've disabled it and restarted.

So far, no crashes! I will report back again after I have had a few more hours of use.

batguano

Yep, that definitely fixed it! No crashes since turning off the UpdateInfo plugin.

Thanks everyone! :-D
