Where can we get the python pretty printer? and how do you load them into GDB?

We don't know what your ~/.gdbinit is, so could you please give us the steps in
your ~/.gdbinit?

            Bug ID: 16505
           Summary: internal SIGFPE busy-CPU locks up GDB
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal

When SIGFPE happens in GDB (for example due to corrupted DWARF file):

Actual:
  PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND
22602 jkratoch  20   0  243188  90680  39960 R  97.3  1.5   0:12.50 gdb
+
GDB under GDB:
Program received signal SIGFPE, Arithmetic exception.
0x00000000007d076e in process_die (die=0x2531c40, cu=0x23d1b80) at

Expected:

A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) _
