This might be fixed already just it was not marked as a regression.

I managed to create a standalone test program. Attachment "aguix.cc" contains
the stripped down critical code segments. The two other files "aguixtest.cc"
and "aguixtest.hh" are just to make a runnable binar

There is a git mirror of the svn repo.
Anyway, -fsanitize=undefined enables -fno-delete-null-pointer-checks, perhaps
you could try that option alone if it makes a difference.

You might want to try -fsanitize=undefined and/or -fno-strict-overflow as it
sounds like you may be invoking undefined behavior.

Small update: The working 32 bit target was gcc 4.7, so it's not related to
this bug.
