------- Comment #14 from rguenth at gcc dot gnu dot org 2008-08-12 15:16 -------
Fails for me on a x86_64 -> i586-linux cross
./cc1 -quiet -O3 -ftrapv /tmp/t.c
/tmp/t.c: In function 'foo':
/tmp/t.c:2: internal compiler error: tree check: expected integer_cst, have
polynomial_chrec in int_cst_value, at tree.c:8078
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
you probably need to configure with --enable-checking.
