For some reason I'm getting more or less random segfaults compiling
kernels, world or PHP5 on BETA-3 (Python and perl went ok). So far I
haven't succeeded building a fresh kernel or world. This system is an
Athlon XP with 1MB RAM and 4GB swap, compiling is done in the usual
places in /usr, which is a set of two gstriped partitions. Dmesg
attached.
Previously this system has been running 5-STABLE w/o any such
problems (uptime before installing 6 was about 80 days, started from
an installworld). This machine doesn't regularly see load yet, except
for the few build(world/kernel)/install(&)s.
I haven't seen any other messages of this kind, so I suspect a local
problem. So far I think I need to look at:
- memory; run memtestx86 and cross fingers
- I recollect seeing mention of problems with large amounts of swap
on this list in the past; turn one of the swap partitions off or
something like that
- Optimization flags; I've tried setting CPUTYPE?=athlon-xp and
CLFAGS=, CFLAGS=-O -pipe, CFLAGS=-O2 -pipe so far. All w/o avail...
- gcc 3.4.4, awk, PHP are all borken (all were built using gcc 3.4.4,
I suppose)
I'm a bit low on spare time, so I'd like to tackle this problem
efficiently. Anything I forgot or to help me find the culprit?
Regards,
