Hmmm, well, here's the comment I found in the strmid function:

* NOTE: This routine does not re-allocate memory to hold the
* shortened string in order to avoid unneccessary fragmentation
* of virtual memory. It simply uses the existing string memory
* (moving the trailing null character up) unless the resulting string is
* null (in which case it is freed).

So, bug? Feature? Undesirable side effect?
