--- Comment #1 from Alexandre Oliva <aoliva at gcc dot gnu.org> ---
Mine.  I suspect this is a symptom of a latent bug in the internal line number
generator in GCC, that's exposed by the LVU patch as it switched to that
generator when the assembler doesn't support views in .loc directives.

After the patch went in, there was general consensus that we didn't want to do
that, and there's a patch pending review that will get disable location views
by default when assembler support is not available.

Please let me know in case that patch fails to address the problem, before or
after it goes in (if it does)
