The leak notices and other --enable-debug messages seem to be brokwn right
now.
ie.
stick a stray char *s = emalloc(20); somewhere and try running php
script.php from the command line. I get a segfault that looks like this:
#0 0x406ab75c in _IO_vfprintf (s=0xbfffeca0, format=0x8186e40 "%s(%d) :

That mem_header looks a bit messed up. I could of course be stepping on
memory elsewhere. Anybody else seeing this?
