Hey all-
I was doing some app debugging tonight, and noticed what appears to
be a memory leak in vfprintf(). I've tested it on -CURRENT and -STABLE;
any program that makes use of vfprintf() (ie, uses printf) appears to
have a 4096 byte memory leak. The memory is allocated on the first
vfprintf() call and is never deallocated. I've observed the memory leak
on -CURRENT as of 30 Jul and -STABLE as of 29 Jul. It was also
reported, indirectly, on ports@ on 21 Jul. The memory leak has been
observed using dmalloc (devel/dmalloc; dmalloc.com) and NJAMD
(sourceforge.net/projects/njamd). I suspect that there may be a similar
leak in vsprintf() as well. I did file a PR (misc/55181), but I thought
I should maybe give a shout-out to the list as well.
