[Bug c/41945] New: [4.5 regression] tree_check failed

[hideaki at sogetthis dot com]

While compiling kernel parts, I got an internal compile error. Testfile is
attached.

$ gcc-4.5 -c ch.i -o ch.o
ch.i: In function ‘nf_ct_tuplehash_to_ctrack’:
ch.i:19:65: internal compiler error: tree check: expected integer_cst, have
nop_expr in int_cst_value, at tree.c:9619
Please submit a full bug report,
with preprocessed source if appropriate.

gcc45 is from opensuse/repositories:/home/rguenther/openSUSE_11.1/i586.
The previously available RPM (20091029) did not have this issue.

GOOD: gcc version 4.5.0 20091029 (experimental) [trunk revision 153698] (SUSE
Linux) 

BAD:
$ gcc -v
