Hello Paul,

I like the approach of narrowing the issue with 'while(1);' and suggest to go further (see below).

I'd move the 'while(1);' into the for loop like follows.

enum { STOP_AT = 0U };
unsigned i = 0;
for (void (**func)() = &CTORS_C; func != &CTORS_G; ) {
    if (i == STOP_AT) while (1) ; ;
    (*func++)();
    ++i;
}

In my case the ctors table has only 2 entries.

With STOP_AT == 1 it hangs, With STOP_AT == 2 it reboots.

I think I will mail you my hypervisor file (now compiled with STOP_AT == 1) in case you want to check it.
