Description of problem:
I was compiling linux kernel 2.6.20-rc1 for UML, and since the UML was not working, I changed the CFLAGS to be -g3 -O0.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Change CFLAGS in kernel Makefile to include -g3 -O0
2. Compile kernel 2.6.20-rc1 with ARCH=um
3. Removed some inline from some functions to make it compile - too much info to specify in this short form
net/ipv4/ip_output.c: In function ‘ip_output’:
net/ipv4/ip_output.c:208: internal compiler error: Segmentation fault

The preprocessed source that generated the error
Fixed in gcc-4.1.1-31 and above (e.g. FC6 testing updates now has 4.1.1-47.fc6).
FC5 updates will have the same codebase when they are prepared.
