hey y’all

i have an app that parses tons of data and does magic tricks

it runs great with smaller amounts of data

but when it runs for several minutes with tons of data it crashes like this :

##############
Exception Type: EXC_BAD_ACCESS (SIGSEGV)

i can’t find any documentation on UASLookupIDForScript

i’m trying to figure out what it’s doing at the time of the crash

the line that says : ASExecuteEvent(AEDesc const*, unsigned int, int, unsigned int*)

does it mean that one of my handlers was just called with four parameters ?

or is my problem unrelated to what was going on and more related to memory deallocation

i’ve had this crash with xcode 4 running on lion with and without garbage collection

now on xcode 5 and 10.9 with and without arc i’m having the same crashes

any info or pointers to documentation would be much appreciated

thanks
