as: Bug Criteria
10.1 Have You Found a Bug?
==========================
If you are not sure whether you have found a bug, here are some
guidelines:
* If the assembler gets a fatal signal, for any input whatever, that
is a 'as' bug. Reliable assemblers never crash.
* If 'as' produces an error message for valid input, that is a bug.
* If 'as' does not produce an error message for invalid input, that
is a bug. However, you should note that your idea of "invalid
input" might be our idea of "an extension" or "support for
traditional practice".
* If you are an experienced user of assemblers, your suggestions for
improvement of 'as' are welcome in any case.
