Confirmed.  The frontend fails to re-map the labels in the asm goto statement
leading to disagreement at gimplification time:

    stmt <cleanup_point_expr 0x14248dbb8 type <void_type 0x14233abd0 void>
        side-effects tree_1
        arg 0 <asm_expr 0x142324b40 type <void_type 0x14233abd0 void>
            side-effects public
..
            arg 4 <tree_list 0x14248dac8
                purpose <string_cst 0x142489f40 constant "other"> value
