No this is correct, it's return value and it corresponds to backtraces:

#0  0x00000000104c90c4 in ._Z19tsubst_template_argP9tree_nodeS0_iS0_ ()
#1  0x00000000104c9294 in ._Z20tsubst_template_argsP9tree_nodeS0_iS0_ ()
#2  0x000000001049a3dc in ._ZL25get_partial_spec_bindingsP9tree_nodeS0_S0_ ()

vs.

#0  0x00000000104c90c4 in ._Z19tsubst_template_argP9tree_nodeS0_iS0_ ()
#1  0x00000000104c92a4 in ._Z20tsubst_template_argsP9tree_nodeS0_iS0_ ()
