In some cases, calls to/from switch construct cases require jumps beyond the
range of the thumb branch instruction. In this case, jumps are made using the
thumb bl instruction, which may be corrupted. The attached example has some
local variables, one of which is held in the lr register and is subsequently
corrupted by both default cases and the return from all other cases, which use a
bl instruction.
