Question about GLR parsing with bison 2.3

[Pierre PICARD]

I have a problem using bison 2.3, I read the documentation, but I did not found 
what I was searching for.
Here is my problem :
I'am writing a GLR parser, and I would like to do a semantic check in a 
semantic action that would have the following behavior if the check fails :
- while a deterministic analysis (with only 1 stack) : display a syntax error.
- while an analysis with multiple stacks : simply kills the current stack.
I would prefer to do that in a semantic action instead of during the semantic 
analysis, is it possible ?
Thanks for your answers.
