[Bug gdb/10944] New: Assertion `get_frame_type (frame) == DUMMY_FRAME' failed

["domen at cba dot si" <sourceware-bugzilla at sourceware dot org>]

Hello,

backtrace at the end.

GNU gdb (GDB) 7.0.50.20091110
This GDB was configured as "--host=x86_64-unknown-linux-gnu --target=arm-none-eabi".

Occasionally I hit this when debugging remote ARM target connected via JTAG/openocd.
I do not know how to reproduce it, it just seems to happen a few times a day
during debugging sessions.

Hmm... gdb says something about inconsistent state, and then asks two questions,
I tell him to quit and dump the core file, which has the backtrace:
