mips64 gdb problem

[Maxim Osipov <maxim dot osipov at gmail dot com>]

Hello,

I have a problem trying to debug 64-bit mips binary with gdb-6.3. It
fails with the following message:

/home # gdb 64test
GNU gdb 6.3

This GDB was configured as "mips64-linux-gnu"...
../../gdb-6.3/gdb/dwarf2-frame.c:1411: internal-error:
decode_frame_entry_1: Assertion `fde->cie != NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)

Sections of this binary looks like the following:

mips64-linux-gnu-objdump -h 64test

64test:     file format elf64-tradbigmips
