yes. this is on amd64 with g++ 4.1.1-21. you need to add -gstabs+ to
get the compiler to crash (fro the latest vamos from cvs):

Car.cc: In constructor 'Vamos_Body::Car_Reader::Car_Reader(std::string, std::string, Vamos_Body::Car*)':
Car.cc:604: internal compiler error: output_operand: invalid expression as operand

remove -gstab+ or change -O2 to -O0 and the file compiles just fine.
