The testcase checked into mainline is causing kernel panics on my debian
testing ia64-linux machine when I run the gcc testsuite. The kernel panic is
coming from the out-of-memory killer, when it runs out of processes to kill. I
have 2GB main memory and 2GB swap. I tried a x86-linux hosted cross compiler
to ia64-linux, and I see the cc1 process uses 3GB before the kernel kills it.
I suspect a 32-bit x86-linux process can't use more than 3GB. I don't know how
much memory is needed for this testcase, but it is clearly too much.
