Subject: bug#45552: 28.0.50; bootstrap-emacs apparently not correctly codesigned
Date: Wed, 30 Dec 2020 14:10:46 +0100

The following happens for me (on macOS Big Sur on ARM 64, which needs
codesigning) pretty frequently: every time Emacs needs to re-dump as
part of `make', the code signature for bootstrap-emacs is somehow
invalid.  For example:

$ ./config.status
[...]
$ gmake
[...]
/bin/sh: line 3: 18759 Killed: 9               EMACSLOADPATH= '../src/bootstrap-emacs' -batch --no-site-file --no-site-lisp -l autoload --eval "(setq generate-autoload-cookie \";;;###diary-autoload\")" --eval "(setq generated-autoload-file (expand-file-name (unmsys--file-name \"calendar/diary-loaddefs.el\")))" -f batch-update-autoloads ./calendar
[...]
$ src/bootstrap-emacs 
Killed: 9

The crash reports for these crashes say

Exception Type:        EXC_BAD_ACCESS (Code Signature Invalid)
Exception Codes:       0x0000000000000032, 0x0000000104098000
Exception Note:        EXC_CORPSE_NOTIFY

Termination Reason:    Namespace CODESIGNING, Code 0x2

However, `codesign' thinks the signature is valid:

$ codesign -v -v src/bootstrap-emacs
src/bootstrap-emacs: valid on disk
src/bootstrap-emacs: satisfies its Designated Requirement

Removing src/bootstrap-emacs and running `gmake' again fixes the issue
(until the next re-dump).
