Version-Release number of selected component (if applicable): gcc-4.1.1-1 How reproducible: Always 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 Actual Results: net/ipv4/ip_output.c: In function ‘ip_output’: net/ipv4/ip_output.c:208: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://bugzilla.redhat.com/bugzilla> for instructions. Preprocessed source stored into /tmp/ccO5Lw9n.out file, please attach this to your bugreport. Expected Results: The file should have been compiled Additional info:
Created attachment 144266 [details] 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.
