Re: [creduce-bugs] creduce crash

Ok, I pushed a fix for this to master, would you mind testing it out, Dmitry?

The fix is to abort with a message saying what happened. I don't believe there's any point in attempting to continue a reduction when our basic mechanism is failing.

When running creduce in 80 threads it crashes with the following message:

I use creduce top of the trunk from github - creduce 2.6.0 (b02c375).
If I run with default 4 threads reduction succeeds, but for me runnning
in 80 threads in more typical usage case, so would be nice to fix it.

To run reproducer in the attachement, build latest gcc and latest clang,
edit path in test.sh, and run:
creduce --n 80 test.sh func.cpp
