Bug #: 56799 Summary: Runfail after r197060+r197082. Classification: Unclassified Product: gcc Version: 4.9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: tree-optimization AssignedTo: unassig...@gcc.gnu.org ReportedBy: ysrum...@gmail.com Created attachment 29766 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29766 Testcase to reproduce the failure. We got Runfail on the attached test-case which was extracted form 254.gap (spec2000). The problem looks like a check on type widening was missed in this fix.
