Thanks for following up on this.
Here's a guess: there's a bug in scan-skel.l, or a bug in flex and/or
the DEC native compilers, which manifests itself on that platform, but
only when a single lex token is larger than an input buffer and the
buffers need to be reallocated.
Does this compiler define __STDC__ to 0 in user code, and leave
__cplusplus undefined? If so, that might explain the problem. Can
you please try inserting the following lines at the top of
and then "rm src/scan-skel.o src/scan-gram.o", and then "make".
I assume that HAVE_STDLIB_H and HAVE_UNISTD_H are 1 in config.h?
If not, that might also explain the problem.
If defining those two symbols doesn't solve the problem, can you
please try this workaround instead? It modifies scan-skel.l so that
large lex tokens are much less likely. You'll need 'flex' installed
to generate scan-skel.c. I'm using flex 2.5.4.
