Re: [Bug-gnubg] Possible problems with python (maybe specifically python 2.7)

[Michael Petch]

That's not good. I'll look at this. I use Python(and have done work in
gnubgmodule.c)  but don't think I build with -Warray-bounds . I assume
you have forced -Warray-bounds on for your builds? I hadn't seen these
particular warnings before, so that's why I am asking.
