Segmentation Fault

[Arne 'Timwi' Heizmann]

Dear Bison developer community,

in my attempts to write a parser using Bison, I have encountered a 
situation where Bison returns a segmentation fault. After long 
experimentation, I found out that it occurs whenever I declare a 
non-terminal, and create a production rule for it, but never use the 
non-terminal on any right-hand side.

Now that I know about this, I'm fine, but I can imagine a lot of users 
are stumped by this. For that reason, it might be worth fixing in the 
next release.

Thanks!
Timwi
