I don't know. However, it is not uncommon that bugs in programs change
with compiler options.

gdb isn't really reliable with high optimizations.

I just briefly tried to debug it, but apparently, it even wants a
Yahoo password or something. This is more effort than I want to spend
on something that I suspect isn't even a gcc bug (and frankly, I
wouldn't expect anybody else to jump in).
