On hppa2.0w-hp-hpux11.11, on mainline between 20050627 and 20050630 both at
07:00 UTC, the failure
FAIL: g++.dg/opt/inline4.C (test for excess errors)
appeared, the error being compile-time stack overflow.
http://gcc.gnu.org/ml/gcc-regression/2005-06/msg00121.html
shows the same failure appearing on Darwin. I can reproduce the problem on
i686-pc-linux-gnu if I use "ulimit -s 4096", while a 4.0 branch compiler works
on the same testcase with "ulimit -s 256". I don't know how much stack the test
needed just before the failure appeared.

This was caused by: "Copy debug info properly in the inliner": http://gcc.gnu.org/ml/gcc-patches/2005-06/msg02022.html What is happening is that we are getting more BLOCKS which seems to link to each other which is weird. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22380 ^ permalink raw reply [flat|nested] 4+ messages in thread
