I don't know anything about the symbol mangling, but the symbol of main is  
actually _Dmain.  main() is the runtime's main which ends up calling your  
main function.  I'm pretty sure gdb doesn't know this.

Likely, the runtime is compiled without the debug flags, so you won't get  
any line info there.

Try breaking on Dmain instead.
