I'm getting sig11s running gcc. I know that that generally indicates
memory problems; what I'm at a loss to explain is how that can be
The machine in question is a Thinkpad T21. I have two 256M SODIMMs.
Either alone works fine. With both in, I get sig11s.
The obvious answer is a motherboard problem. I thought that, too,
so I sent the machine back to IBM; they, in turn, replaced the
motherboard. So I have a new motherboard, and two memory cards
that alone work just fine -- but together, they don't work.
What other problems could cause this? Heat? Would it generate
less heat if I tried doing the same thing (building the whole source
tree) while on battery, which would slow down the CPU? A virtual
memory problem in the kernel? The machine in question is running
a 1.6_STABLE kernel from six weeks ago.
