Re: [Gems-users] "parser stack overflow" while building protocols

[Mike Marty <mikem@xxxxxxxxxxx>]

This is wierd.  We use the same version of bison however the generated
parser.c file is slightly different.

Regardless, this seems to be a known problem with bison 1.875:

http://lists.gnu.org/archive/html/bison-patches/2003-05/msg00000.html

I will try to figure out WHY we get a different parser.c (I have also
e-mailed this to Nauman already...if anybody else needs it to continue
working, let me know).

Bison 2.0 is out as well and I will try this as well.
