I'm mainly waiting to hear feedback (including my own) about "I use it
with no visible problem".

I do.

Do you have the file&line number at least?

More important than that is the ENABLE_CHECKING (which you apparently
was using already anyway) and running under a debugger: even if
optimizations may throw GDB off a bit, it's usually good enough to make
progress on the bug (sometimes by adding more assertions or printfs to
make up (next time around) for the lack of info provided by GDB).
