QtCreator crashes

  • 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:

    Any advice appreciated!

    Hi and welcome to devnet,

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

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

  • I've submitted a bug report, QTCREATORBUG-12964

  • Lifetime Qt Champion

    Ok, good, thanks for sharing the link

  • Hi, I see in your crash log QTimerInfoList::activateTimers(), and there are many bug reports filed for that function, like "this one":

    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).

  • 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.

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

    Thanks everyone! :-D
