Bug #: 53812 Summary: lower_stmt (4.6), verify_gimple_stmt (4.7.0, 4.7.1) Classification: Unclassified Product: gcc Version: 4.7.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: 0ez...@gmail.com Created attachment 27719 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27719 preprocessed source The attached code causes internal compiler error for 4.6.3, 4.7.0, and 4.7.1. Same reported location as #53356 but happening in 4.7.1. I was unable to reduce to a smaller example that would still expose the problem. Here is the full output of g++ -v -save-temps (for g++-4.7.1) Using built-in specs.
