We are hitting an annoying x87 FPU design flaw. You can read all about it here if you are interested: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=323 And there is a good paper on it here: http://hal.archives-ouvertes.fr/docs/00/28/14/29/PDF/floating-point-article.pdf We don't need any more compile reports. If you are on an architecture that uses the x87 FPU and you haven't forced SSE or float-store then you will see this problem. ------------------------------------------------------------------------ [2011-01-04 19:11:29] hieu dot ld at vnnb dot net Re: last comment, I believe "-mfpmath=sse" did the trick. apologies for cluttering the bug report. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
