Bash Version: 5.0
Patch Level: 0
Release Status: release

Description:
  When `builtin bind --help' is executed in Bash 4.4 and 5.0,
`begin_unwind_frame ("bind_builtin")' is called, but `run_unwind_frame
("bind_builtin")` is not called.

Repeat-By:
  With my bash configuration, the following command causes actual
problems. But I omit a detailed explanation because my configuration
is too complex to explain here, yet the problem is rather clear.

  $ builtin bind --help

Fix:
  In `builtins/bind.def', the macro `CASE_HELPOPT' is expanded to
something like `builtin_help(); return (EX_USAGE);'. However, here
`return' should be replaced by `BIND_RETURN`. I attach a patch for the
devel branch.

Best regards,
Koichi
