Have you tested with dmalloc? (Sorry to say, I too haven't got the time to
track anything down just now. Maybe tomorrow.) I have tried both one.
With dmalloc, I seem to get sometimes something like reasonable results.
I mean ,something like this (the end of the log) (there are a few
malloc()s not free()d I put in functions/gd.c to track down where I'm
going at, they have already been fixed, just not yet committed) (objects.c
& parseAFM.c & t1base.c & t1set & t1aaset.c are from t1lib).

dmalloc really helped me to track down a few quite-hard-to-find bugs in
t1lib. Can't say the same about efence. But, using dmalloc is a major
PITA. Maybe a switch to help this? --enable-debug-dmalloc or
enable-maintainer-mode-with-dmalloc ?
