No, PEXEC assigns the whole free memory to a program IIRC. I know this from a loader app I wrote.

But it may make trouble anyway if you run a GEM program, although there is already a GEM program running.

As I told, the TOS on Atari STs was a single task OS.

One problem I see is, that PEXEC in an accessory will halt the accessory, and that's something, that must not happen. This should interrupt the message loop and may stop all GEM activities.

4 bombs means illegal instruction, i.e. the program counter comes to a byte sequence that is definitely no MC68000 instruction.

In other words: the "instruction cursor" lands in a data block, not program code.

This may come from a corrupt stackpointer...
