It's difficult to say what the problem is without a complete listing
of the source assembly line causing the fault and the contents of all
the registers.

But in almost all cases I have seen so far, V2 execution failures have
been related to programs expecting uninitialized memory (stack/malloc)
values to be set to zero when first accessed, which V2 no longer does
(unless you include crt0.h and set a special flag to zero the memory).
