I see this here too. Apparently this was caused by the i386.h PUSH_ROUNDING
change of this patch:

PR target/25293
* expr.c (emit_move_resolve_push): Handle PRE_MODIFY
and POST_MODIFY with CONST_INT adjustment equal to PUSH_ROUNDING.
Fix POST_INC/POST_DEC handling if PUSH_ROUNDING is not identity.
* config/i386/i386.md (pushhi2, pushqi2): Use pushl instead of
pushw.
Set mode to SI, adjust constraints.
(pushhi2_rex64, pushqi2_rex64): Set mode to DI.
* config/i386/i386.h (PUSH_ROUNDING): Round up to 4 instead of 2 for
32-bit code.
The push_operand predicate does not allow pushes with a mode that does not
agree with PUSH_ROUNDING.
