Re: Pb with Bison on Unix

[Hans Aberg]

If one uses %union, the C parser is supposed to be dynamic, and when  
not using it, I think Joel E. Denny said he is setting some Bison  
macro to achieve it (I do not remember details). If you set  
YYMAXDEPTH, I think you get a initial static array, so if it is too  
big, the parser will break.
