Both optimization options compiled the code, and successfully executed the testsuite. I found it strange that it was only -O2 that had a failing testsuite, since -O3 should include the same inline optimization as -O2. I forgot to mention in my previous mail, my testing was done on non-native hardware. I will take your advice and change it to -O1, thanks for taking the time. Regards, Håvard
