The following code snippet triggers an ICE when compiled with -fno-exceptions:
=================== void f() { try {} catch (...) {} } =================== bug.cc: In function 'void f()': bug.cc:9:10: error: exception handling disabled, use -fexceptions to enable bug.cc:10:1: internal compiler error: in gen_eh_region, at except.c:351 Please submit a full bug report, [etc.] The bug appeared between 2009-10-02 and 2009-10-10. Btw, that's the same problem as PR1054 which was fixed for GCC 3.0 :-( -- Summary: [4.5 regression] ICE with try/catch and -fno-exceptions Product: gcc Version: 4.5.0 Status: UNCONFIRMED Keywords: ice-on-invalid-code, error-recovery, 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=41819
