I compile with GCC 3.4.3 and max optimizations on Solaris and I do not have any problems.
Try it and see if it works with -O3 -fexpensive-optimizations. FYI, in my case, it only got about 2 secs faster on a 1.5 minute test run. HTH!

For linux (i686/Fedora Core 3/gcc 3.4.2 and x86_64/SuSe 9/gcc 3.3.3), is there any danger in using -O2? Does anyone has experience in using -O2? successful or problematic? My compilation configuration is: ./runConfigure -plinux -minmem -nsocket -tnative -rpthread I add -b64 in x86_64. Thanks a lot in advance. -- Best Regards, Chris Cheung ___________________________________________________________________ The information contained in this message and any attachment may be proprietary, confidential, and privileged or subject to the work product doctrine and thus protected from disclosure.
