I experienced the following failed assertion when debugging Cortex-M4F code using floating point.

GCC-4-8-build/src/gdb/gdb/regcache.c:178: internal-error:
register_size: Assertion `regnum >= 0 && regnum <
(gdbarch_num_regs (gdbarch) + gdbarch_num_pseudo_regs (gdbarch))' failed.


All routine that pass a floating point value to the routine will failed when I set a breakpoint inside the routine. GDB crashes as soon as the break is encountered.
