[Bug testsuite/38605] New: Out of stack space on gcc.c-torture/compile/limits-exprparen.c

[howarth at nitro dot med dot uc dot edu]

Since at least r138218, the regress test for powerpc-apple-darwin8.5.0 has been
showing the new failures of...

FAIL: gcc.c-torture/compile/limits-exprparen.c  -O0  (test for excess errors)
FAIL: gcc.c-torture/compile/limits-exprparen.c  -O1  (test for excess errors)
FAIL: gcc.c-torture/compile/limits-exprparen.c  -O2  (test for excess errors)
FAIL: gcc.c-torture/compile/limits-exprparen.c  -O3 -fomit-frame-pointer  (test
for excess errors)
FAIL: gcc.c-torture/compile/limits-exprparen.c  -O3 -g  (test for excess
errors)
FAIL: gcc.c-torture/compile/limits-exprparen.c  -Os  (test for excess error

The last build without these failures was r138218 but there was a large gap in
builds during the tuples merge. The failures are logged as...

Out of stack space.
Try running 'ulimit -S -s unlimited' in the shell to raise its limit.
compiler exited with status 1
output is:

Geoff Keating suggests this indicates the test is no longer testing if the
stack space for gcc is reasonable. I don't see this on a dual G5 with 4GB of
ram running darwin9 but regress is a G4 with less ram (I assume) running
darwin8.
