For these, it would be useful to get the line number and stack trace of the
crash; you can get it by using gdb.
  (gdb) run
  (gdb) where

For this one, additionally the instruction of the crash would be interesting.
  (gdb) run
  (gdb) where
  (gdb) x/10i $eip
  (gdb) info registers
  (gdb) info float
