I looked a bit more, tried to remember how the jit and process changes
work and I do hit:
if UNCOMMON (!IS_NIL (switch_to_process))
{
change_process_context (switch_to_process);
if UNCOMMON (single_step_semaphore)
{
printf("SINGLE STEP...%p %d %d %d\n", thisContext,
TO_INT(thisContext->native_ip), ip,
TO_INT(thisContext->ipOffset));
_gst_async_signal (single_step_semaphore);
I stepped through the emitted code for the interrupt check and I do
see that _gst_ip is not 48 at that time and the thisContext->ipOffset
is != FROM_INT(48).

I am puzzled of where it is set. So far I will have a look at the
interrupt checks and see if _gst_this_context_oop is set correctly.
anyone else got an idea of what I should look at/verify?
