Description Marc Lopez 2001-08-10 08:11:57 EDT

Description of problem:
When I try to compile the kernel, I got segfault.
All patches mentioned in RHBA-2001:082-05 advisory are applied.
The crashes are random. When I do 'make bzImage' and crashes, I make again 
and crashes but in any other file. The file that crashes before, now is 
compiled without error, and so on... 
Finally, after executing 'make bzImage' several times, the kernel is 
compiled and runs perfectly.


How reproducible:
Always

Steps to Reproduce:
1. Untar kernel sources
2. Compile the kernel

	

Actual Results:  Random segfaults compiling kernel making bzImage

Expected Results:  Compiling kernel without errors

Additional info:

I got the same segfaults compiling ssh 3.0

Comment 1 Jakub Jelinek 2001-08-11 15:16:52 EDT

If you get random segfaults (as opposed to reproduceable failures
of gcc), it means in 99.9% cases you have flakey hardware.
gcc stresses the CPU and the memory subsystem very hard, so even if
other programs work fine, it does not mean your hardware is sane.

Ok! Thanks for your help. I will look for a possible H/W failure.
