It's highly environment sensitive; in a testsuite run, the only one that
failed on me was limits-pointer at -O3, but when I run the compile command
from the shell directly, it fails at any -O level. It looks to me:
Program received signal SIGSEGV, Segmentation fault.

... like we're trashing the stack somewhere in the debug output generation.
Hmm, hang on:
(gdb) info regis
eax 0x0 0
ecx 0x1a0d790 27318160
edx 0x1b1e93c 28436796
ebx 0x7fb3b240 2142483008
esp 0x42ff0 0x42ff0
ebp 0x43008 0x43008
Yeh, that's very wrong: those values should have been 0x0023xxxx. Looking
briefly through memory, it seems we've /massively/ underflowed the stack... I
see this repeating pattern that looks a lot like a stack-frame all the way up
from 0x0004xxxx right through memory as far as I could be bothered looking
towards 0x0023xxxx.
