version(GNU)
{
    import gcc.builtins;
    __builtin_trap();
}

Portable, but you can't continue the program as with int 3. GCC really
needs a __builtin_break.

There's also
version(Posix)
{
    import core.sys.posix.signal;
    raise(SIGTRAP);
}

which allows to continue the program. The breakpoint is in the C
raise function in libpthread however and not in main as with your mixin.
