After realizing that my gimp 2.0.2 build was failing, and seeing numerous mmx and sse related issue, I decided to ask around. It appears that someone was able to compile on athlon xp (which appear to have mmx and sse use flags disabled) and someone with gcc 3.4 was able to correctly compile. This causes me to belive that gcc 3.3.3 improperly handles mmx and sse compiling. In order to prove this, the following test case should be tested: 1. For same arch purposes, this test should be conducted on a pentium 4 system. 2. CFLAGS should be set to "-O2 -mcpu=pentium4 -pipe" Case 1: gcc 3.3.3 is used gimp 2.x builds should fail on certain mmx and sse functions Case 2: gcc 3.4.x is used gimp 2.x builds should succeed I have already proven test case 1, as I hope someone else will. Another dev has proven test case 2. Reproducible: Always Steps to Reproduce: Actual Results:

This bug is cpu related more than anything else. Because of the small ammount of registers on 686's (as stated by a similiar gcc bug), less aggressive cflags must be used. That means taking down -O's a notch if possible. Consider this almost like an openoffice build.. only smaller :), try and be nice on the flags. Closing this bug as invalid, since gcc is not the apparent issue.
