Try a C compiler or clang++. It's working for you due to a g++ bug.

Don't bother fixing it. I'm going to inline this routine anyway because I
want to be able to use it in MatSetValues where we don't want to have to
save registers to do the search.

To make it more useful, should we return the location that the new item
would go?

So if we search for 5 in [2,4,7,8], we return -3. The calling user code
would look like

PetscFindInt(...,&loc);
if (loc < 0) insert_at = -(loc+1);

Or a different routine for that purpose?
