Hi all,
I'm working with a program utilizing Core Text, but occurred to some strange
problems. When trying to reformat a document
larger than 1MB, the program crashes with the following error msg:
malloc: *** mmap(size=4,294,598,656) failed (error code=12)
*** error: can't allocate region
*** set
Any explanations for the jump?
Well, *if* an exception was thrown, of course the rest of the method was
skipped over. That's what happens when an exception is thrown, all code all
the way up the stack is skipped until the next matching catch block.

Since you're asking to instantiate the string with NSASCIIStringEncoding, the
method could return nil when it fails to convert the pBuffer contents (i.e.
non-ASCII bytes above 0x7F).
That would lead to trigger exception raises at the line immediately following.
