font book allows users to add new "collections" of fonts with a name of thier choice. When the name of the collection is a very very very large string of characters it crashes. here is the gdb output: _____________________________________________________________ (gdb) run Starting program: /Applications/Font Book.app/Contents/MacOS/Font Book Reading symbols for shared libraries ........................................................................... done Reading symbols for shared libraries . done Reading symbols for shared libraries . done Reading symbols for shared libraries . done Reading symbols for shared libraries . done Reading symbols for shared libraries . done Program received signal EXC_BAD_ACCESS, Could not access memory.
