Illegal instruction address (TRAP B)

Hi,

My build is successfull but when running on hardware, I'm facing a Trap B interrupt. (HW is ST10F276)
I followed the http://www.keil.com/support/docs/2534.htm tutorial and found:

   tfr = 2
   illegal instruction address = 0xE083D


... but this address does not correspond to any addressable space in my linker file...
I tried to pop some bytes from the stack to know where the PC is coming from but difficult to interpret...

Any ideas ?

thanks a lot
