Aargh. I filed the bug report in the morning and completely forgot
about it when I started to do a total reorganization of the
webservers.. The url should work now but you might still have the old
ip address of lindi.iki.fi in cache.

best regards,
Timo Lindfoirs

I cannot reproduce this problem.
I use w3m 0.5.2-9, libgc1c2 1:7.1-3 and 1:6.8-1.2.
I do not get GC Warning and no SEGV.

Upstream maintainer says get GC Warning but no SEGV.

If this problem still exists,
please show dependency libraries version, especially libgc.

Seems that today w3m just gets killed by the out of memory
killer. (And amazingly it also causes so much swapping that the
network ups tools (nut) timeouts which might be a bug in nut):

Maybe it depends on how much memory you have? I had only 128 MB at that
time I think.

I have 2G memory.  I think w3m does not considere so low memory,
so I am afraid that it will not fix.  If you need fix absolutely,
I will forward it again.

128 MB is all the memory that my openmoko phone has. But don't worry,
I've already switched to lighter browsers like elinks, midori and
chromium ;-)

OK, I mark upstream wontfix and close it at present.
But I will forward it again for hope to fix in future.
I am apologize to have troubled you so much.
