[MACTCL] wish app crashes sporadically

[Robert K. <ro...@na...>]

a wish-aqua app crashes sporadically at different points on different machines
often as soon as it starts up.
I see this error appearing in the console. Does anyone have any idea what the cause is
(and I don't have experience using any c debuggers on the mac)
This is 8.4.9 on OSX 10.3.9. The app. is almost entirely tk scripts, with only some minor
changes to c code that have been there for a long time (and don't use malloc).
Thanks for any help.
