Do we have a CPUTYPE=native and/or generic stability problem?

The machine has 12 MB RAM (no swap configured), after nearly a day
uptime it looks like this:

---snip---
Mem: 348M Active, 599M Inact, 9281M Wired, 264K Cache, 1548M Free
ARC: 7117M Total, 1607M MRU, 3996M MFU, 934K Anon, 208M Header, 1307M Other
---snip---

I would not expect an internal compiler error when I run out of RAM.

---snip---
 # gcc -march=native -v -c -x c /dev/null 2>&1 | grep -- -march
 /usr/libexec/cc1 -quiet -v -D_LONGLONG /dev/null -march=core2
 -mtune=generic -quiet -dumpbase null -auxbase null -version
 -o /tmp//cc7kc0JI.s

Bye,
