VM page fault

[Tom Chandler]

I am trying to understand/read what Minix3 is telling me on a
program. I am running "tracking current".

VM: pagefault: SIGSEGV 1206571 bad addr 0x2b; err 0x4 nopage read
PM: coredump signal 11 for 7148 / miniruby
miniruby 1206571 0x2b 0x843ff28 (hbp 1 ?)

Is there documentation to read / understand the above, and can anyone
explain the above messages.

My guess? is miniruby is trying to access a location that does not
exist. If so how do you
debug to locate the error?

Thanks

Cheers

Hi Tom,

That's a NULL dereference. Perhaps a function pointer in main() that
wasn't properly initialized?
