Porting bison to z/OS (ASCII based)

Hi,

I am starting to port bison to z/OS and am curious about the best way to go about debugging. When I go to run ‘bison’ on the sample rpcalc program, e.g.

Echo “4 9 +” | make run

it is getting killed due to stack overflow when running bison. I imagine this is either because of some recursion in bison or a bug in our alloca() on z/OS, although it’s a bug so who knows 😊

I poked around for some docs, and the docs said to come here… Appreciate your help. And – if someone else has recently tried to port bison to z/OS (64-bit ASCII preferred), would love to share!

Thanks, Mike
