+[low-mem] Fix DW_OP_GNU_parameter_ref handling in read_exprloc
+
+Function read_exprloc contains a loop that marks all parents of a
+DW_OP_GNU_parameter_ref reference with CK_BAD.  The loop however has no
+private loop variable, so the ref variable, initially pointing to the
+referenced DIE, ends up after the loop pointing to the root parent of the
+reference instead.  Consequently, the code after the loop, intended to be
+executed for the referenced DIE, is instead executed for the root parent of
+the referenced DIE.
+
+Fix this by moving the loop alap.
+
+2019-02-14  Tom de Vries  <tdevries@suse.de>
+
+	PR dwz/24195
+	* dwz.c (read_exprloc): Move loop marking parents with CK_BAD alap.
