re PR target/70633 (ICE on valid code at -Os (in 32-bit mode) on x86_64-linux-gnu: output_operand: invalid expression as operand)
PR middle-end/70633
* gimplify.c (gimplify_init_constructor): Clear TREE_STATIC if
gimplification turns some element into non-constant.
* gcc.c-torture/compile/pr70633.c: New test.
