Try updating to at least

PR middle-end/36671
* tree-ssa-structalias.c (handle_lhs_call): Add flags argument,
handle calls from ECF_MALLOC functions.
(handle_pure_call): ECF_MALLOC functions do not return
call-used memory.
(find_func_aliases): Handle all calls, adjust calls to
handle_lhs_call.

Richard.
