LINUX: Crash when closing workspace

User forums > Using Code::Blocks

<< < (2/2)

rickg22:
Try with the "extra stability" (aka "crash protection") enabled... also, mind posting the backtrace?

Joker:
here's a backtrace of a similar error, different spot (still same reason, I'm sure.. faulty tree as someone already said) WITHOUT extra stability enabled:

here it is WITH extra stability enabled (appears identical to the orignal poster's error now):

its not 100% crash in either case (with, or without extra stability). it seems rather random. sometimes, works, sometimes doesn't... though there seems to be a more of a chance it happening with more projects open.

Hope that helps!

BTW, I'm running the latest CVS (as of this posting)

st3vie:
i've been away for a while :)

i haven't been able to really get to the bottom of this. As stated by joker, it is a bit random. One time it's with the first project i try to close, then it's with the 6th, the next time with the 3rd.

It's a strange one i guess. Maybe i'll have some more time again soon to try to dig alittle deeper.
