The problem is specific for 64 bit environments, made these: gcc -Wall -msse -mno-sse2 -I. -lm -DSOFT_SSE2 -DEMMSOFTDBG \ -O0 -m32 -S -o gccprob_wno32.s gccprob.c gcc -Wall -msse -mno-sse2 -I. -lm -DSOFT_SSE2 -DEMMSOFTDBG \ -O0 -m32 -o gccprob_wno32 gccprob.c gcc -Wall -msse -msse2 -I. -lm -DSOFT_SSE2 -DEMMSOFTDBG \ -O0 -m32 -o gccprob_nono32 gccprob.c gcc -Wall -msse -msse2 -I. -lm -DSOFT_SSE2 -DEMMSOFTDBG \ -O0 -m32 -S -o gccprob_nono32.s gccprob.c
and both binaries work correctly. Added them to the set here: http://saf.bio.caltech.edu/pub/pickup/gccprob.tar.gz Specifics on the environment where the problem is seen: OS: Mandriva Linux release 2010.0 (Official) for x86_64 gcc (GCC) 4.4.1 Dual Dual Core Opteron 280. Arima HDAMAI motherboard. 64 bit targets only, 32 bit is OK. Regards, David Mathog mat...@caltech.edu Manager, Sequence Analysis Facility, Biology Division, Caltech
