It's easiest to explain with an example: % cat test.c #include<stdio.h> int main() { return printf("\n"); } % gcc test.c -o test ; ./test >/dev/null ; echo $? 10 % gcc test.c -o test -fno-builtin ; ./test >/dev/null ; echo $? 1 There are few applications that rely on *printf's return value for such simple strings, but there is at least one in portage (xchat). It removed all server info except for the first for me, because it used fprintf's return value to check for errors and stopped writing the rest of the servers. Reproducible: Always Steps to Reproduce: This seems to be caused by 08_all_gcc34-chk.patch.bz2. A manual installation of gcc 3.4.3 doesn't have this problem. It still didn't have this problem after I applied gcc-3.4.3-branch-update-20050110.patch.bz2. But when I applied that, I got the above results. (I had to reinstall my system for other reasons after I first ran into this bug, so I can't give accurate emerge --info, but I asked on the forums and I'm not the only one with this problem, so I hope you can forgive me :) If you can't reproduce this, I'll install it again and give you my emerge --info after that.)
gcc 3.4.4 doesn't work correctly either. This bug has gone without any comment for over three months. Please, would someone either remove that broken patch, or fix it?
considering someone (lv i think, no idea really) just ripped it from fedora, i dont mind punting it completely it looks like the features it adds are cool, but if we cant maintain it, then no point in keeping it ;)
punted patch from current ebuilds as well from our patch repo
