Steve,
for kicks, do the following:
void deAllocSource()
{
UInt16 index ;
UInt16 err;
char a[100];
for (index = 0; index < 100; index++)
{
if (sourcel[index] != NULL) {
err = MemPtrFree(sourcel[index]);
ErrFatalDisplayIf(err, "problem with memptrfree'ing one of the sourcel
array members");
err = MemPtrFree(sourcelist[index]);
ErrFatalDisplayIf(err, "problem with memptrfree'ing one of the source
strings");
}
}
g_source_array_count = 0;
return;
}
I only recommend this because you don't mention how you allocate the
array (whether or not you fill holes or just add to the end of the array
when removing adding strings) and you don't mention how you increment,
decrement g_source_array_count in your allocation routine when adding
strings (is the the number of
elements in the array, or is it the max element in the array)....
I suspect that your intermitent errors are a result of removing items
from the array, your not compressing the array, and g_source_array_count
isn't the MAX element, it's the number of elements in the array.
Now, if I'm all off base here, you can see how hard it is to answer
folks questions when they don't explain EVERYTHING related to the
problem (which of course is pretty impossible...but, we do the best we
can..)
Cheers and Good luck!
