[antlr-interest] Segmentation Fault under Cygwin 1.5.18-1

[McCall, Kurt]

Here is a gdb stack trace after a mystifying segmentation fault in my C++
ANTLR parser running under Cygwin 1.5.18.1.  It seems to be crashing the in
the Cygwin dll.   Does this look familiar to anyone?  The ANTLR version is
2.7.5.

Program received signal SIGSEGV, Segmentation fault.
