M5329EVB C Stationary - ISR trouble on CW 6.4

I got a problem with the interrupt handling in the M5329EVB C stationary.
The vectors.s is the standard one that came with the stationary, and I placed a
breakpoint in the low level ISR handler for testing.

It does not even reach the handler function, the moment any ISR is thrown,
it says "Exception vector name: Illegal instruction".

From what I've read, the illegal instruction in the ISR vector could be caused by a bad
memory layout that overwrites the interrupt vector with the heap.
(sounds reasonable to me, but I expected a little more from the stationary).
I tried reducing the heapsize as suggested, but that does not help.

I'd be glad for any help or ideas here
