Created attachment 40647 [details] bzip2'ed preprocessor output at -O1
This one happens only at -O1 -- worked perfectly with -O2 and -O3 before switching to -O1 because of another gcc bug.
Works at -O0, as well - it's specific to -O1.
Can reproduce this with 3.1-0.10, cannot reproduce with CVS, assume it has been fixed.
