The reason of corrupted output is because of a wrong signature.

 /*******************************

This patch, however, only gives the __FILE__ and __LINE__ of the druntime
function, not the actual user code that emits the error.  But I think this
can't be fixed without modifying DMD because _aApplycd1 doesn't contain the
line information.
