Well I'm not a Mac guy, but malloc I'm familiar with.  Under the
hood it's Unix anyway.  I'd be happy to take a look at it.

Is that Mac totally reliable with other programs?  What I'm looking
for is temperature extremes causing memory/CPU errors and such.  If
you've added memory recently, changed your CPU or cpu speed, or
updated your OS recently, you may want to wait a bit to see if
everything is stable.

Also, are you now running Xastir for longer timer periods, or on the
'net feeds longer or have more feeds connected?  It's possible that
the memory size of Xastir has now grown up into an area of
questionable memory on the computer.  I've had the problem before,
and it took extensive memory tests to find the problem.

Any other Mac OSX users having similar problems?

P.S.  Of course it could be a very simple Xastir coding problem that
is causing it.  Just trying to check all possibilities!
