Description basic 2004-12-06 22:28:48 UTC 
with gentoo-dev-sources 2.6.9-r1/6/9 oom killer kills my mozilla debug compile at linking the layout lib (biggest lib).
 I have 128MB RAM with 392MB of swap.
 I'm using -Xlinker --no-keep-memory, -Xlinker --reduce-memory-overhead in my LDFLAGS.
 This has never happened in 2.6.8-r10, I'm about to emerge the latest 2.6.8 to test it. According to htop/top there's still free swap space available when this happens. Below is the tail from my /var/log/messages

Reproducible: Always

Normal per-cpu:
cpu 0 hot: low 12, high 36, batch 6
cpu 0 cold: low 0, high 12, batch 6
HighMem per-cpu: empty

forgot to mention that this is on a x86 (athlon). And just found out that -r10 is the latest 2.6.8 for x86 (though it seems to be not listed on packages.gentoo.org)
Comment 2 Daniel Drake (RETIRED) gentoo-dev 2004-12-07 04:47:57 UTC 
Can you please try with development-sources-2.6.10-rc3? I think it should be fixed there
Comment 3 basic 2004-12-07 16:30:13 UTC 
tested with development-sources-2.6.10-rc3, problem seems to be fixed there.
Comment 4 Daniel Drake (RETIRED) gentoo-dev 2004-12-14 01:12:25 UTC 
Ok, could you please apply this patch against 2.6.9 and let us know if it fixes the problem?

Tried it against gentoo-dev-sources-2.6.9-r9, it fixes it.
Comment 6 Daniel Drake (RETIRED) gentoo-dev 2004-12-15 15:15:13 UTC 
Fixed in 2.6.9-r10
