GDB 7.11 start error

I've installed gdb 7.11 via, pkg install gdb-7.11 ... When I try to run it, gdb gives me this error;

i386fbsd-kern.c:482: internal-error: _initialize_i386_kgdb_tdep: Assertion `offsetof(struct pcb, pcb_ebx) == i386fbsd_pcb_offset[I386_EBX_REGNUM]' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) [answered Y; input not from terminal]

This is a bug, please report it.  For instructions, see:
<http://www.gnu.org/software/gdb/bugs/>.

Abort (core dumped)

I can't debug my core files, because I'm using g++ 4.9 compiler, so I should use 7.11...

My system: FreeBSD local.com 9.2-RELEASE FreeBSD 9.2-RELEASE #0 r255898: Fri Sep 27 03:52:52 UTC 2013 [email protected]:/usr/obj/usr/src/sys/GENERIC i386

Thanks in advance.

At first glance it looked like an ABI problem, but it's more like GDB is doing something really stupid: it tries to use kernel backend for the kernel version it doesn't know about, even though it doesn't need the backend at all - since you're debugging userspace, not the kernel.

You should submit a PR about this (http://bugs.freebsd.org).
