	PR middle-end/65003
	* varasm.c (place_block_symbol): Assert that DECL_RTL of the
	ultimate alias is MEM with SYMBOL_REF satisfying
	SYMBOL_REF_HAS_BLOCK_INFO_P as its operand.  Don't pass the MEM
	to place_block_symbol, but instead pass the SYMBOL_REF operand of it.

	* g++.dg/opt/pr65003.C: New test.
