Not necessarily. You could try adding -mapcs-frame to the
CYGBLD_GLOBAL_CFLAGS option. You could also try reducing the optimization
level from -O2 to -O1 or disable it (-O0) just to see if that makes a
difference; or you could also try disabling the CDL options
CYGDBG_HAL_COMMON_CONTEXT_SAVE_MINIMUM and
CYGDBG_HAL_COMMON_INTERRUPTS_SAVE_MINIMUM_CONTEXT

Let us know if one of those fixes things for you.
