Most versions of malloc return a pointer to a zero-length part of the
heap when you ask them for 0 bytes.  Some versions of malloc return a
NULL pointer then instead, which is indistinguishable from an out of
memory error.  Either add a line to xmalloc which checks for a request
for 0 bytes and changes it to a request for 1 byte, or use a debugger
to find out where the request for 0 bytes is coming from -- it's
probably an error, since there is no point in allocating 0 bytes.
