--- Comment #2 from Fritz Mueller <fritzm at fritzm dot org> ---
In case it is helpful:

I recently ran into this also.  Interestingly, the heuristic for deducing the
.text start address from the entry point is in fact still there and still
active (it's at bfd/aout-target.h:55.)

As it turns out, the heuristic is only applied when the entry point is in a
different *page* than the .text VMA, and the defined PDP-11 page size was
changed 256 -> 8192 in PR 20694 after the release of 2.33.1.

In my case, I found bumping my .text relocation and entry point up to 0x2000 in
order to correspond to the increased page size did, in fact, result in the
return of the "old" behavior of the tools, including alignment of symbols with
.tex disassembly in objdump and otherwise better-behaved conversions to other
formats via objcopy.
