Thank you for filling out a Git bug report!
Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)
Create a signed git tag signed by a SSH key and run this command
(orginally executed by goreleaser).
% git -c log.showSignature=false tag -l --format='%(contents:body)' v4.2.2

What did you expect to happen? (Expected behavior)
Command executed successfully

What happened instead? (Actual behavior)
% git -c log.showSignature=false tag -l --format='%(contents:body)' v4.2.2
fatal: Out of memory, malloc failed (tried to allocate
18446744073709551323 bytes)


What's different between what you expected and what actually happened?
See above

Fixed by b01e1c7ef0 (ref-filter: fix parsing of signatures without blank
lines, 2022-11-02).  It hasn't made it into a release, yet, but I would
expect it to be included in an upcoming version 2.38.2.  Discussion:

I am fairly certain it would be in 2.39 but probably not 2.38
maintenance track, as b01e1c7ef0 seems to have been applied without
considering that it is a maint-worthy material.
