--- Comment #9 from Johan Tufvesson <tuben at lysator dot liu.se> 2012-12-11 08:08:45 UTC ---
I think that I see this problem all the time using an ARM Cortex-M3 with a
FlashPro4 JTAG from Microsemi. The connection to the JTAG is done through an
"arm-none-eabi-sprite" from the CodeSourcery environment. No multiple cores
here. It is possible to make one call into the inferior (using call or print),
but when returning from the second call GDB chokes. I'm quite new to both the
GDB and ARM environment, but everything works as expected when running the
target. I'm only having trouble when calling into the inferior from GDB, and
the problem is always exactly as below, the second call into the inferior.

If I take a step after the first call returned, I can make a second call
without problems. If I then take another step, a third call can be made. The
problem only occurs (with 100% certainty) at the second call from the same
spot.

I would be very grateful for any help on this, and would be happy to try out a
patch. The GDB 7.5.1 in this case have been built by me, but the faulty
behavior is exactly the same using binaries from the CodeSourcery or Yagarto
tool chains.
