pc686: --enable-rtems-debug not working

[Jan.Sommer at dlr.de]

Hello,

if I build the pc686 BSP with --enable-rtems-debug activated I can't run any of the testsuites examples, but get the following error:

$ qemu-system-i386 -append --console=/dev/com1 -no-reboot -serial stdio -monitor none -nographic  -kernel ./build/i386-rtems5/c/pc686/testsuites/samples/ticker.exe  
i386: isr=0 irr=1
assertion "bsp_interrupt_is_valid_vector(vector)" failed: file "../../../../../../../../refex-rtems/c/src/lib/libbsp/i386/pc386/../../../../../../bsps/i386/shared/irq/irq.c", line 275, function: bsp_interrupt_vector_enable

*** FATAL ***

It seems to stem from rtems/bsps/i386/pc386/clock/ckinit.c:165:

> bsp_interrupt_vector_enable( BSP_PERIODIC_TIMER - BSP_IRQ_VECTOR_BASE );

because "BSP_PERIODIC_TIMER - BSP_IRQ_VECTOR_BASE" equates to 0xFFFFFFE0, but the subsequent assert on bsp_interrupt_is_valid_vector() only allows vectors between 0 and 16.
The BSP still works with the option disabled, but it makes debugging more difficult.
Does someone has some guidance on this problem. I could remove the assert in bsp_interrupt_vector_enable, but I am a bit hesitant with simply removing things from core files.

Best regards,

   Jan
