Command-line options? Neither -O[23] -g seem to reproduce it,
at least based on top of PR49879 fix...

Nevermind, I got it -- -fomit-frame-pointer.
The problem is that H8 allows eliminable registers in push insns.
This leads to elimination failures.
C.f. the i386 register_no_elim_operand predicate, which is the
solution to things like this.
