Bug #: 53460 Summary: Internal compiler error: in calc_dfs_tree, at dominance.c:395 Classification: Unclassified Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: middle-end AssignedTo: unassig...@gcc.gnu.org ReportedBy: li...@carewolf.com Compiling webkit with either -fprofile-generate or -fprofile-use will cause GCC to ICE on several different files. Under any other compile flags GCC compiles the same files without any problems. There are one other open bug that ICE at the same place in GCC, but seeing that several older bugs have the same line, I assume that is no guarantee that the bug is the same, and the other bug is not related to profiling. I have included two examples, but have not reduced them.
