And it's come back again recently. Only -O2, not -O3, required this time.

bug120.cc
activemq/commands/ActiveMQBytesMessage.cpp: In member function ‘bool
activemq::commands::ActiveMQMessageTemplate<T>::propertyExists(const string&)
const [with T = cms::BytesMessage; std::string = std::basic_string<char>]’:
activemq/commands/ActiveMQBytesMessage.cpp:668:1: internal compiler error:

Please submit a full bug report,

I think there may be some value in making sure that the source code
of all new bug reports, before reduction, compiles ok at -O2 or maybe -O3.
