This used to be in a FAQ somewhere...when compiling C++ apps one has to
compile with -O. You can compile with -O -g and get most of your debug
symbols (though your inlines will be optimised). This is due to a bug in
g++ that has been rather elusive when trying to track it down.

hope that helps,
tom
