Hello:
I have a microscopy program that displays and acquire images, and
saves processed images. I keep getting crashes in my program in a
function that is called from [ NSSavePanel
runModalForDirectory:file:types ]
The program crashes very often (every 20 calls roughly) at
THFSPlusStore::LessThan(HFSUniStr255 const&). I have tried many things
(including passing empty strings or nil strings for all parameters to
runModalForDirectory:file:types etc...) and I can't see what is wrong.
I may have some corrupted memory somewhere because of another thread
(?), but I can't come up with a good strategy to find it. In another
issue, I often get the message "CGImageSourceCreateWithData data
parameter is nil" in my logs but I have been absolutely unable to
track down what Cocoa function calls that function.
Any help would be greatly appreciated.
Daniel
