I just tried to compile Suse Linux package opensp-1.5.1-120 with the GNU C++ compiler version 4.3 snapshot 20070302.
The compiler said URLStorage.cxx: In member function 'OpenSP::HTTP_RESPONSE_TYPE OpenSP::HttpSocketStorageObject::readHeader(OpenSP::Messenger&, char*)': URLStorage.cxx:601: error: definition in block 74 does not dominate use in block 77 for SSA_NAME: NMT.1285_487 in statement: NMT.1285_354 = PHI <NMT.1285_485(ab)(69), NMT.1285_487(77), NMT.1285_487(78), NMT.1285_485(ab)(68), NMT.1285_485(ab)(71), NMT.1285_487(74)> PHI argument NMT.1285_487 for PHI node NMT.1285_354 = PHI <NMT.1285_485(ab)(69), NMT.1285_487(77), NMT.1285_487(78), NMT.1285_485(ab)(68), NMT.1285_485(ab)(71), NMT.1285_487(74)> URLStorage.cxx:601: internal compiler error: verify_ssa failed Please submit a full bug report, with preprocessed source if appropriate.
