Hi Mark,

I get the following information:

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000002
0x929b9831 in get_uint32 ()
(gdb) c
Continuing.

And the same error again and aagin. Don't know how to proceed further, 
seems to hang infinite

Regards,

Sebastian
