Is there a special rule that compilers will always initalize
uninitialized scheme values to zero?  Because I discovered a
segfault just yesterday (in a different program) that was because
of gcc [1] not initalizing a variable to 0.

[1] or rather, the C standard does not specify that an
uninitalized variable should be set to 0, so I do not blame gcc in
the least; it was the programmer at fault.
