re PR middle-end/36817 (internal compiler error: in compare_values_warnv)
2008-08-21 Richard Guenther <rguenther@suse.de>
PR middle-end/36817
* tree-chrec.c (chrec_apply): Always call chrec_fold_plus which
makes sure to produce a result of the correct type.
* gcc.c-torture/compile/pr36817.c: New testcase.
