The following valid code snippet triggers an ICE since GCC 3.4.0: ======================================= void foo() { { static const int& i = 0; } { static const int& i = 0; } } =======================================
bug.cc:4: error: redefinition of 'int _ZGRZ3foovE1i' bug.cc:3: error: 'int _ZGRZ3foovE1i' previously declared here bug.cc: In function 'void foo()': bug.cc:4: internal compiler error: in layout_decl, at stor-layout.c:305 Please submit a full bug report, [etc.] In addition the error message before the ICE is bogus, since the code is valid. The error message was introduced in GCC 3.1. -- Summary: [4.0/4.1/4.2 regression] ICE/rejects-valid with references Product: gcc Version: 4.2.0 Status: UNCONFIRMED Keywords: ice-on-valid-code, rejects-valid, monitored Severity: normal Priority: P3 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: reichelt at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28338
