	PR middle-end/82253
	* expr.c (expand_assignment): For CONCAT to_rtx, complex type from and
	bitpos/bitsize covering the whole destination, use store_expr only if
	the complex mode is the same.  Otherwise, use expand_normal and if
	it returns CONCAT, subreg each part separately instead of trying to
	subreg the whole result.

	* gfortran.dg/pr82253.f90: New test.
