iPhone3gs applications running problem

Met a fairly depressed,
When commissioning will always hang, gdb information is
gdb-i386-apple-darwin (6036,0 xa0140540) malloc: *** error for object 0x1585320: pointer being freed was not allocated
*** Set a breakpoint in malloc_error_break to debug

Check with malloc_history not see any information,
In single-step execution, without any problems, everything is normal, although gdb or show the same error, but will not let the program collapse out, directly continue, then, will be stuck, but finding any tips
