This reply shows an interesting aspect of compiler development that is
often overlooked: The social aspect.
Compiler writers generally want to improve their product, but they
also generally feel that bug submitters (at least those who don't have
a support contract) should also invest a minimum of work if he wants
something fixed, and a general "look at large package xyz, it'll be
obvious" is below that threshold. (This is the reason why gcc, for
example, asks for a complete and self-contained test case in its bug
People who complain about bugs, but are not willing to put in that
minimum amount of work, are often ignored.
