re PR target/41985 (Internal compiler error reported.)
PR target/41985
* config/i386/i386.c (get_some_local_dynamic_name): Don't assert
function contains at least one local dynamic name.
(print_operand) <case '&'>: Instead output operand lossage diagnostics
here if that happens.
* gcc.target/i386/pr41985.c: New test.
