Well, I spent today finishing off the BGCCache integration, and getting
blackbox to compile on IRIX with MIPSpro 7.3.1.1m
Our IRIX machine has Purify on it, so I cleaned up the only UMR's i could
find (UMR = uninitialized memory read). Here is a report showing that
blackbox has no memory leaks (however, many library calls do leak, mostly
in Xlib). Quite pleasing to say that blackbox had no memory leaks even
before I started running it through purify.
For those interested, here is the (relatively empty) purify log.
