27d4fb96 PP	218	/* XXX LEAKTEST doesn't really work in perl5. There are direct calls to
	219	safemalloc() in the source, so LEAKTEST won't pick them up.
	220	Further, if you try LEAKTEST, you'll also end up calling
	221	Safefree, which might call safexfree() on some things that weren't
	222	malloced with safexmalloc. The correct "fix" to this, if anyone
	223	is interested, is to ensure that all calls go through the New and
	224	Renew macros.
