	PR c++/81675
	* cp-gimplify.c (cp_fold) <case COND_EXPR>: Don't return immediately
	for VOID_TYPE_P COND_EXPRs, instead fold the operands and if op0 is
	INTEGER_CST, ensure that both op1 and op2 are non-NULL and fall
	through into normal folding, otherwise just rebuild x if any op
	changed.

	* g++.dg/warn/pr81675.C: New test.
