https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82737 --- Comment #6 from Matti Bryce --- I have figured out more information. For some reason the build command in the log was (erroneously) listed as -O2, but the actual trigger of the segfault is -O3. I am running creduce right now, but the size of the file means that it is going to take many many hours more. However, I have uploaded the .i.cpp file and the python3 detector script so you can easily run it if you have a more beefy computer. The folder containing all 3 things is: https://bitbucket.org/TheEdenCrazy/gassim/src/a01812e2f7d95e667f67d400bb9d57caad1a5709/_gcc_bug_test/?at=master (just cp Manager.cpp.i -> Manager.cpp.i.cpp), then do creduce ./attempt_compilation.sh Manager.cpp.i.cpp To reduce it.

I've attempted to reduce a test case, but after 2 days of running creduce, the produced file won't generate the error. I'm going to run gdb now.(In reply to Martin Liška from comment #5), and see if I can do anything with it (though if someone could give me tips for what to look for, that'd be great).

Thanks. I added a backtrace (though my GCC doesn't have debug symbols). It seems the stack is corrupt at some point.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82737 --- Comment #10 from Matti Bryce --- If anyone knows how to get gcc with debug symbols, that'd be useful, because I could get a better stack trace.

Looks you hit stack overflow. In that case, please use ulimit and set > smaller stack, that will simplify the reduction.

But I can't find the configure option on https://gcc.gnu.org/install/configure.html, so if you could tell me the flag to use to enable debug symbols, that would be helpful. I'm running creduce again, so I'll get back to you on that once it has finished running. Thanks. Thanks.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82737 --- Comment #17 from Matti Bryce --- (In reply to Martin Liška from comment #16) > Matti: Any progress with the reduction? Yeah, it's reduced about 20% or so. But it's taken several days just to get this far, so it's going to be quite a while before anything usefully small come of it.
