 I guess I'm supposed to reply directly to you instead of appending a note to 
 the bug since I cannot find where to create an account. Sorry for the 
 attachment being cut off, I used 'gccbug' and I did not see a watch to do an 
 "attachment", so I copied and pasted the preprocessor text as requested.
 
 I installed gcc snapshot 20021021 and compiled the same preprocessed code that 
 failed on 3.2 and it compiled on this snapshot (the version says 3.3). So you 
 can close this bug and fixed.
 
 Thanks!

 I just thought that I'd add to this bug, since I've had the same issue. =
 The=20
 problem seems to be caused by the -mfpmath=3Dsse flag in combination =
 with the=20
 pentium4 (as far as I can tell). I've run into this bug only twice. =
 Once when=20
 compiling the gsmatrix.c file previously mentioned and the other when=20
 compiling postgresql-7.2.3, the src/backend/utils/adt/float.c file. =
 I've=20
 compiled these same files on a pentium3 (using -march=3Dpentium3 and no =
 -sse2)=20
 and on an athlon-xp (using -march=3Dathlon-xp and no -sse2, but also =
 having=20
 -m3dnow) and the bug does not occur in these situations. I've =
 reproduced this=20
 bug on pentium4 and pentium4-m (mobile) processors. Hope this =
 information=20
 will be of help.
