Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Download mozilla source 2001-10-12-08-trunk/ 2. ./configure 3. make Actual Results: Make failed Expected Results: Should have compiled. Additional info: When file is built by hand it works. May be a hardware fault, I suppose.

Download mozilla source 2001-10-12-08-trunk/ ) 2. ./configure 3. make and when it fails at step 3, repeat running "make" to see whether it fails always on the same file. If it doesn't, check your memory chips with: http://www.memtest86.com
This appears to be a very subtle motherboard/processor fault. I can only get the build to fail on this machine. Swapping the memory has no effect.
