[Qemu-devel] Patch for minor qemu heap corruption bug when the console is zero width |

Hi everyone, here is another patch for a much less significant bug. If
your "vc" console width is 0, qemu corrupts the heap (because it
writes one character into a screen buffer that's been malloc'ed as
size 0). I don't know if this bug ever causes problems in practice
--- I picked it up using mcheck() when debugging heap corruption due
to various slirp bugs. Anyway, this trivial patch fixes the trivial
bug. Feedback on what I can do to get patches like this applied most
appreciated!
Thanks,
-Ken
