Ideally, what we'd really need from the Debian team are:

1) the file that gets miscompiled, and
2) the -f flag which causes it

(1) is essential.  (2) would be nice but not crucial.  The "easy" way to
find (2) is to compile with "-fFOO" where FOO is one of the flags
turned on by -O2, as listed in the manual.  Iterate over the list until
you find the FOO that causes the breakage.  Building with "-O2 -fno-FOO"
should give you all the /other/ benefits as well as working code.

This goes much faster, of course, if you can identify (1), then you only
have to recompile that file.
