It was using uninitialized data on the stack.

I have installed a (hopefully) correct fix for this, preserving the
intention of only clearing what's being used.

BTW, I also installed another fix a hour ago or so, but it wasn't ok,
as it caused emacs to loop in GC.  My latest fix (properly handling
re-entrance to read_avail_input) seems to work alright.

If there are still problems, I suggest to revert keyboard.c back
to revision 1.761.
