MALLOC_CHECK_=1 - Debugging information.
MALLOC_CHECK_=2 - Abort on invalid malloc() data.
I would recommend _against_ putting 'export MALLOC_CHECK_=1' in your
startup profile unless you want to check 'ls', 'gdb', 'pine' and every
other application on your hard drive. The syntax at the top sets the
variable only for that program. This will _not_ work with Linux libc 5.x,
I tried with 5.4.44.
This may save hours of hair torture in your CircleMUD (see? it's related)
debugging.
