Need help to execute/debug smpschededf02.exe on leon3

[Richi Dubey]

On executing run again on gdb, I am getting the following error:

0x00000000 in ?? ()
(gdb) run
The program being debugged has been started already.
Start it from the beginning? (y or n) y
../../gdb-9.1/gdb/thread.c:95: internal-error: thread_info*
inferior_thread(): Assertion `tp' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) y

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

../../gdb-9.1/gdb/thread.c:95: internal-error: thread_info*
inferior_thread(): Assertion `tp' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Create a core file of GDB? (y or n) y
Aborted (core dumped)


What might be going wrong?
