Is this a gdb bug? -- internal-error: decode_frame_entry_1: Assertion `fde->cie != NULL' failed.

Hi guys,
        I runs  gdb on a system which based on fedora core 1. I had tried the
gdb 5.3 which bring with fc1, gdb 6.0/6.3 (rebuild) from other fedora
version. But I always got the following error:

(gdb) n
The program is not being run.
(gdb) q

Is ths a bug?  And what's the reason? I've tried other version of gcc
-- (3.3.3, 3.3.6) too.

Best regards.
