SIGSEGV is a bad memory reference, but none of those URLs gives any info

the program counter value, the contents of the instruction stream.
The pastebin info is useful after that, but knowing the SIGSEGV info comes first.
The minimum info for a SIGSEGV report is:
(gdb) thread <N> # focus on the faulting thread
(gdb) info reg # display all machine registers
(gdb) x/5i $pc # the faulting and following instructions
(gdb) x/12i $pc-0x20 # probable previous instructions (heuristic for x86*)
Thanks for the pointers I just wish I understood it more...
Thanks,
Richard
