Hi, I have recently upgraded to Quad-Core AMD Opteron(tm) Processor 2384 from Dual Core. I have started getting core dump from a 3rd party library from CyberSource. This is output from uname -a: Linux pqvault301v 2.6.9-34.EL #1 Fri Feb 24 16:44:51 EST 2006 i686 athlon i386 GNU/Linux and gcc -v [pqvault301v:pqaprod] $ gcc -v Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/specs Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --enable-languages=c,c++ --disable-libgcj --host=i386-redhat-linux Thread model: posix gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-47.3) The program terminated with signal 11, Segmentation fault.
