talloc()

[Gerald Carter]

Here's a little be on interesting information...

two consecutive calls to talloc() of 0 size will return 
pointers to the same memory location.  This has come up in 
prs_unistr().  If the amout of allocated space needed is 0,
the the str->buffer will still get assigned a memory address
by prs_alloc_mem().

**and the next prs_unistr will get the same memory!

Hmmm....My gut says that the first UNISTR should have its buffer
set to NULL instead.  Any reason why not?  I'll play with it 
and see.




Cheers, jerry
