> You need to provide self-contained testcase, this is not self-contained.
Thank you for running your simple experiment. Unfortunately, all my attempts to
create a simple self-contained test have failed. Of course, during this
process, I did play with exactly the same code you did.
I have been aware of this problem for several months. I decided to file a bug
without a test because the problem appears to be critical and I hope somebody
who knows the optimization code might spot the issue.
All I can add is that my project is about 110k lines of code, the function in
question is in a .cpp file of about 560 lines. But I doubt it helps very much.
