Problem with ptype $<user register>

[Paul Hilfinger]

For the simple "hello world" program appended, the command sequence

    b main
    run
    ptype $pc

causes an internal GDB error:

   .../gdb/regcache.c:163: internal-error: register_type: Assertion `regnum >= 
0 && regnum < descr->nr_cooked_registers' failed.
   A problem internal to GDB has been detected,
   further debugging may prove unreliable.

when run on i686 GNU/Linux with recent sources:

     GNU gdb 6.6.50.20070307-cvs

Program compiled with GCC 4.1.2 derivate.
