Subject: bug#65455: 30.0.50; Disassemble: error with "free-standing" native compiled function
Date: Tue, 22 Aug 2023 15:17:21 +0200

In *scratch*, evaluate

(defun foo (a b)
  (list a b))

(native-compile 'foo)
(disassemble 'foo)

This gives an error in disass.el, around line 98 that a re-search fails,
but the real error might be that, in the lines above, objdump is called
on a file that does not exist.

Workaround is to save the function to a file, native-compile that file,
and load the resulting .eln.  Then the disassemble works as expected.
