Some yacc's for 386s apear to be compiled with rather small tables (yes,
they appear to not allocate memory dynamically... heck, even the output
file name is fixed!).  I had this same problem a few years back with my
Microport UNIX, at which time Microport was kind enough to offer a version
compiled with bigger tables.  I now run Esix and have no problems with the
table sizes anymore.

My guess is that this is your 'out of space' problem:  one of the internal
tables is full.  Perhaps you can talk your UNIX vendor into giving you a
yacc binary compiled with bigger tables.

Cheers. - Rob
