This issue reappeared again.

On FreeBSD 9.0-CURRENT ia64: gcc-4.7.0.20110730 builds fine.

Updating to 4.7.0.20110827 gives this error again:

This issue never was gone for upstream GCC. I had a hack in the lang/gcc47
port on FreeBSD which worked around this which did not apply any more with
the latest snapshot.

Also if you remove files/patch-unwind-ia64.h from the lang/gcc47
port on FreeBSD which I assume you are using?  In the context of
upstream GCC -- that is here ;-) -- please always remove that one
when reporting success or failure.

Yes, *without* files/patch-unwind-ia64.h.

Cool, removing 4.7 from the list of regressing versions then (and removing
that patch from the lang/gcc47 port in FreeBSD).

I don't think this is ever going to be addressed for the older versions
of GCC since nobody knows for sure how it was fixed and there have been
a number of changes around ia64 in the last months.

How is that best reflected in Bugzilla?
