First do

strace /bin/ls

That will tell you what strace calls the brk and mmap system calls.
(They aren't always brk and mmap.)

Then trace the failing compiler, asking for just those calls:

strace -o trace.out -e trace=brk,mmap,munmap ./cc1 <arguments>

Replace cc1 by whichever compiler you're using, and brk,mmap,munmap
with whatever they're called on your system.  Send me trace.out.

Ok, I need to go get lunch anyhow.
