All the options default to off, with the partial exception of the a/A option: the default behavior is not quite the same as either 'a' or 'A'. (By default, it'll complain and abort if the internal structures get corrupted, you make a recursive call, or you pass it particularly bogus pointers. 'a' disables all those, while 'A' makes it also complain and die if allocation would fail. It's probably those default checks that are triggering the alerts you referred to.) > Also, what options do folks use when they want to really test things out? I use this: $ ls -l /etc/malloc.conf lrwxr-xr-x 1 root wheel 4 May 23 21:49 /etc/malloc.conf -> FGJP $ If a program I don't have the time to debug has problems with that then I set MALLOC_OPTIONS=fgjp (or whatever is sufficient) for just that program.
