--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
The issue is likely latent then.  IIRC some x86 sub-targets enable prefetching
by default.

It's a very odd place for a segfault btw, which might suggest some memory
corruption (also explaining the preprocessed reproducer failure).

I'd try using a watchpoint on the bogus pointer from the bitmap list walk,
it should be initialized from the points-to pass running before PRE and
stay valid from there.
