Bug #: 51601 Summary: ice in verify_live_on_entry Classification: Unclassified Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: dcb...@hotmail.com Created attachment 26121 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26121 gzipped C++ source code I just tried to compile the package drumstick-0.5.0-1 on latest trunk dated 20111216 on an AMD x86_64 box. The compiler said dotLength_28 is defined in BB6, by: dotLength_28 = PHI <dotLength_38(5), dotLength_41(6)> It is also live-on-entry to entry BB 2 So it appears to have multiple defs. /home/dcb/rpmbuild/BUILD/drumstick-0.5.0/library/src/qove.cpp: In member function 'int OVE::NoteContainer::getDuration() const': /home/dcb/rpmbuild/BUILD/drumstick-0.5.0/library/src/qove.cpp:4580:5: internal compiler error: in verify_live_on_entry, at tree-ssa-live.c:1444 Please submit a full bug report, with preprocessed source if appropriate.
