Re: [patch/rfc] Use frame_type for sigtramp test in infrun.c

based on other discussion, I suspect the test will need to be: 

if (frame_id_inner (this_frame_id, step_frame_id)
    || frame_id_eq (....))

the former is to handle a signal delivery that resumed the inferior at the signal handler and not the signal trampoline. 


Won't anywhere you do that frame_id_inner test add another breakage for
sigaltstack?

Hmm, true. Sigaltstack will break any inner test.
