--- Comment #10 from Pedro Alves <palves at redhat dot com> --- It sounds that way, but I haven't verified, e.g., by trying older versions of gdb, and/or bisecting. Kevin, in addition to trying older versions of gdb with freorder-blocks-and-partition, I'm curious about why gdb finds different ends of prologue when stepping vs when setting a breakpoint. It may be that making both spots use the same logic (e.g., it may one is skipping instructions manually using the heuristic unwinders and another is using the line tables) will be good enough of a stopgap to unblock this bug.
