gcc-bug/test-case.cpp:14: internal compiler error: verify_stmts failed It is very simple code that I have used in C++ for a long time. Like this: std::copy(&array[0], &array[5], ostream_iterator<int>(cout, "\n"); I accidentally built GCC 4.5.0 from SVN instead of 4.4 (it branched when I wasn't looking) and hit this bug. It only seems to happen with optimization and profile generation. -O1 -fprofile-generate will trigger it. -O3 without profiling will not. I have not tried to reproduce with GCC 4.4 or GCC 4.5 on i686 or x86_64. Preprocessed source will be attached. -- Summary: -fprofile-generate -O1: ICE: verify_stmts failed, ADDRESSABLE bit not set on pointers passed to std::copy Product: gcc Version: 4.5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: gcov-profile AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: zlynx at acm dot org GCC host triplet: ia64-redhat-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39732
