Created an attachment (id=9018)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=9018&action=view)
Much shorter testcase
I attach another testcase that I managed to get down to approximately 10kloc.
It is only standard include files now, so shouldn't be too hard to reduce
further (if only I had more time...)
It presently gives me this:
spec/src> c++ -O2 -march=pentium4m -msse2 -ftree-vectorize -c x.ii
x.ii:1489: warning: ‘__malloc__’ attribute ignored
x.ii: In constructor ‘X::X()’:
x.ii:10161: internal compiler error: tree check: expected ssa_name, have
var_decl in verify_ssa, at tree-ssa.c:750
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
