Hello,

I'm experiencing random crashes with CBC 2.9.6. The problem is difficult to reproduce. Most of the times by running the same model many times it crashes just once. Looks like an uninitialized variable or something like that.

I already tried on different computers, with different operating systems (Win XP, Windows Server 2012, Linux) with CBC built with different compilers (mingw32 with gcc 4.8.1, mingw64 with gcc 4.9.2, an old Linux server with gcc 4.4.4).

I have been able to get a reproducible crash only under Linux, but if I recompile CBC with debug symbols enabled it doesn't crash anymore. So I'm able to provide only a call stack of the crash, no detailed informations, I hope it's enough.

I attach the model used to get the crash, an execution log and the call stack provided by gdb. Let me know if there's something more I could do.

Thanks in advance for any help.

Bye,

=================

Hello,

this is just to let you know that the crash still happens with 2.9.7. I'm trying again to get a reproducible crash and see if the problem is still the same or if it is something different now.

Bye,
