In testing gcc-4.1-20050716 for i686: I originally ran into the following error
internal compiler error: tree check: expected tree that contains 'decl minimal' structure, have 'record_type' in lookup_decl_die, at dwarf2out.c:5461 on the last line of a program. While starting to come up with a minimal test case, I was surprised to find that although I could reproduce that error with preprocessed source, stripping out the lines starting with # produced a different error: x.ii: In instantiation of '__gnu_cxx::rope<char, std::allocator<char> >': x.ii:42429: instantiated from here x.ii:41107: internal compiler error: in force_decl_die, at dwarf2out.c:12621 This is probably fortunate, since it now dies much sooner than at the end of the program. To reproduce this, unpack http://kegel.com/gcc/ice-rope.ii.gz, then compile it with i686-unknown-linux-gnu-gcc -g -Wall -Werror -funsigned-char -c Apologies for not finding a small testcase, and for using a week-old snapshot for testing. Hopefully this is useful anyway. -- Summary: ICE in force_decl_die, at dwarf2out.c:12621 Product: gcc Version: 4.1.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: dank at kegel dot com CC: gcc-bugs at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23045
