I smell that this is related to FEATURES="splitdebug" will test tomorrow
tried with splitdebug/nostrip, without any of them, without "debug" useflag, no change
have to correct myself... this seems related to USE=debug compiling simple test program fails. It does succeed when clang is compiled without debug useflag: # cat test.c int main () { return 0; } # clang test.c -o test 0 libLLVM-3.2svn.so 0x00007f8df14f4fdf 1 libLLVM-3.2svn.so 0x00007f8df14f5579 2 libpthread.so.0 0x000000378fa0f500 3 clang 0x0000000000609efa std::string::assign(std::string const&) + 234 4 clang 0x000000000080dc5f 5 clang 0x000000000080c288 6 clang 0x0000000000a38bb9 clang::Sema::Initialize() + 25 7 clang 0x00000000009a13b7 clang::Parser::Initialize() + 1063 8 clang 0x000000000099ea88 clang::ParseAST(clang::Sema&, bool, bool) + 152 9 clang 0x000000000080ae5e clang::CodeGenAction::ExecuteAction() + 78 10 clang 0x0000000000667a19 clang::FrontendAction::Execute() + 185 11 clang 0x000000000063f438 clang::CompilerInstance::ExecuteAction(clang::FrontendAction&) + 344 12 clang 0x0000000000618af4 clang::ExecuteCompilerInvocation(clang::CompilerInstance*) + 1988 13 clang 0x0000000000609168 cc1_main(char const**, char const**, char const*, void*) + 1160 14 clang 0x0000000000612ee2 main + 7186 15 libc.so.6 0x000000378f21f28d __libc_start_main + 253 16 clang 0x00000000006089f9 Stack dump: 0.

this seems to be caused by a mismatch of "debug" useflag between clang and llvm when both have -debug it works, when both have +debug it works when clang has +debug and llvm -debug it does not work
(In reply to comment #9) > this seems to be caused by a mismatch of "debug" useflag between clang and > llvm > > when both have -debug it works, when both have +debug it works > when clang has +debug and llvm -debug it does not work The opposite seems to fail as well. Therefore, the dep should be [debug=].
From some older problems we already had with llvm/clang, this does not surprise me. Thanks for hunting that one down, I updated the depend on llvm with "debug=" in all current clang ebuilds
