No. (Not yet).

I think I need CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT too.

I've dome some printf'ing too and the problem is probably the
hal_saved_interrupt_state variable which is used in hal_ctrlc_isr (file
hal_if.c) as an argument to cyg_hal_user_break.

(By the way this variable is declared as a 'struct HAL_SavedRegisters*' and
is transtyped to a 'CYGADDRWORD*' when passed to cyg_hal_user_break which in
turn trantype its argument to plain 'HAL_SavedRegisters*' not a struct... So
far I've only found one arch that defined HAL_SavedRegisters as a struct,
but all define it as a type. It won't compile if you try to access a member
of the struct)

Thanks
