Two comments to this:

1) 3.0.4 is an old version. If you report bugs in open-source programs,
you should always do so with respect to the most currently available
version. In the case at hand, that's 3.0.6, from August 2000

2) I'm not sure at all that AWK is, or has ever been claimed to be, an
8-bit clean program. The behaviour you describe quite nicely fits what
I expect would happen if that was the root of the problem. \372
probably is the internal token or state number of some non-terminal
element in the grammar.
