   The regress tester for powerpc-apple-darwin8.5.0 has been failing...

since http://gcc.gnu.org/ml/gcc-testresults/2008-07/msg02753.html (r138218).
Unfortunately there was a large gap in the regress builds before this (from the tuples
merge perhaps). The last build without the errors was http://gcc.gnu.org/ml/gcc-testresults/2008-07/msg00727.html
of 137613. Geoff Keating suggests the fact that the gcc.c-torture/compile/limits-exprparen.c
now produces the error...

...indicates that it is no longer checking that GCC's stack space is
reasonable. I'll open a PR for this against 4.4.0.

ps I don't see this myself on a dual G5 with 4 GB running darwin9
but regress is a G4 running darwin8 with, I assume, much less memory than that.
