As long as you're building your own copy, how about building with
--enable-debug and getting a stack trace showing where the error is
being thrown?  Setting a breakpoint at exit_horribly() ought to do
the trick.  To be concrete:

    gdb pg_dump
    gdb> b exit_horribly
    gdb> run --port 65432 ... rest of command line for pg_dump ...
    ... wait for breakpoint to be hit, then ...
    gdb> bt
    ... copy and paste the printout here ...
    gdb> quit
