vector-ref error on ___recovery

GoogleCodeExporter commented 8 years ago

There seems to be a problem with the ___recovery function setting ___sp to
a negative value after an error occurs, which causes the parsing loop to
die.  Specifically, at lalr.scm:1871, I get:

  In procedure vector-ref in expression (vector-ref ___stack ___sp):
  Value out of range 0 to 4294967295: -1

If I change line 1830 from

  (if (< sp 0)

to

  (if (>= sp 0)

I seem to be able to get a little bit further, although that doesn't seem
to be the right fix.

Can you provide a parser that reproduces the error? 

Which Scheme system do you use? Which version?
