Sudden crash with new Juce


#1

I recently upgraded an application from Juce 1.21 to 1.38. After modifying here and there everything appears to run smoothly - but only appears. Lately, I’ve experienced mysterious crashes, not seen before the Juce upgrade. The following is a print of the relevant parts of the crash report (sorry about the “dump”). There are some other threads running, so this might be cause of stuff - but appearently not in the earlier Juce version. Any hints, similar experiences or stuff I should know about A complete fix perhaps…? :slight_smile:

-Thanks in advance!

That crash isn’t actually in juce code at all - it’s deep in apple’s own stuff…

Most likely there’s some kind of memory corruption going on, but impossible to say any more from this info. It could be in your code, or in juce. I’ve not seen anything similar.

The mac windowing has all completely changed since 1.21 though. If you could get some code that reproduces the crash I’d be happy to take a look.

Thanks for your reply. I’m afraid it’s somewhat impossible to isolate the bug. It is a biig program, and it actually rarely crashes - so finding out what, when, how and why something goes wrong… Well. If I get a hint of the problem, and can reproduce it reliably, I’ll let you know!

Hi Amygdala, did you ever find out what caused this crash? A friend of mine had a similar problem too on his MacBookPro2.
