Bug #: 53356 Summary: ICE in verify_gimple_stmt, at tree-cfg.c:4258 Classification: Unclassified Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: f...@fuhm.net On the code: test.cpp: =============== class A {}; struct B { operator const A &() const; }; A* cause_ICE() { return new A(B()); } =============== Running: g++ -std=c++0x -c test.cpp With gcc version: g++ (Debian 4.7.0-8) 4.7.0 (which says it's built from r187339 on the gcc 4.7 branch). On architecture: x86-64 Crashes with error message: test.cpp: In function ‘Foo* cause_ICE()’: test.cpp:7:6: internal compiler error: in verify_gimple_stmt, at tree-cfg.c:4258 Removing -std=c++0x makes it not crash. 4.6.3 does not crash. This looks similar to bug 49996, (but obviously different, because that one is still fixed).
