Bug#318932: g++-4.0: [PR 22551] ICE in tree_low_cst, at tree.c:3843

[Johnny Casey <emailwastefilter-reportbug@yahoo.com>]

Package: g++-4.0
Version: 4.0.1-2
Severity: important


See http://gcc.gnu.org/PR22551

I came across this while compiling pose on AMD64 (I am not sure it
will work eventually...).  No problem with g++-3.4.

command line:
$ g++-4.0 -c testcase.cppoutput:
testcase.cpp: In function 'int main(value_type)':
