Subject: [PATCH] Fix for issue #245

* The change fixes the build issue observed in GCC 12.XX.
* Looks like GCC is confusing label to a local variable and hence triggers dangling-pointer error when a label addres is assigned to a pointer.
* Changed branch_to_test from void * pointer to uint64_t datatype since we just need the retrun address of the label while updating the ELR. This should suppress the dangling-pinter warning thrown by GCC 12.XX
