Built using gcc 4.6.3.
--
1. I load an approx. 500 MB capture with sctp/m3ua/isup traffic.
2. I select "Statistics/IO Graph"
3. wireshark crashes in:
get_it_value (io=0x7fef882e7010, graph=0, idx=626018) at io_stat.c:521
dumping a core. it turns out get_it_value tries to dereference a NULL value.
maybe idx is out of range for the array:
io->graphs[graph].items
??
I attach the full trace as shown by gdb for the dumped core.
