Is nexti confused by pushq?

Hi, when I get to the following instructions:

  0x00007fffe192413e: rex.W pushq 0x28(%rsp)
  0x00007fffe1924143: rex.W popq (%rsp)
  0x00007fffe1924147: callq  0x00007fffe1045de0

and do "nexti" at the first, it doesn't stop at the second but instead acts
as though I'd done "continue". For some reason I can't reproduce with a
little test though.

(gdb 8.1 on Ubuntu 16.04)

BTW I'm doing nexti programmatically and trying to avoid looking at the
next instruction to decide whether to do stepi or nexti.

Cheers,

David
