I don't 'spose you can reproduce this with sane cflags, as well, can you ? :) 
Oh, I don't know .. something like CFLAGS="-O2 -march=pentium4 -pipe" ?

Seems the -fweb was problematic. Please apply:

ok added -fweb to the filtering

Please filter out -fno-omit-frame-pointer as well. It makes the compile break
in
the same place as -fweb does.
