What did you do before the bug happened? (Steps to reproduce your issue) When using ssh signing `git tag -l --format='%(contents:body)' <tag>` returns `fatal: Out of memory, malloc failed (tried to allocate 18446744073709551323 bytes)` What did you expect to happen? (Expected behavior) The tag to be returned without crashing What happened instead? (Actual behavior) git crashed with the above error (`fatal: Out of memory, malloc failed (tried to allocate 18446744073709551323 bytes)`) What's different between what you expected and what actually happened? Anything else you want to add: ``` [14:23:54] (0):~/src/github.com/my/repo % git tag -sam v0.0.9 v0.0.9 [14:24:03] (0):~/src/github.com/my/repo % git -c log.showSignature=false tag -l --format='%(contents:body)' v0.0.9 fatal: Out of memory, malloc failed (tried to allocate 18446744073709551323 bytes) [14:24:27] (0):~/src/github.com/my/repo % git tag -sm v0.0.9-no-annotate v0.0.9-no-annotate [14:27:19] (0):~/src/github.com/my/repo % git -c log.showSignature=false tag -l --format='%(contents:body)' v0.0.9-no-annotate fatal: Out of memory, malloc failed (tried to allocate 18446744073709551323 bytes) [14:27:26] (128):~/src/github.com/my/repo % git tag -m v0.0.9-no-annotate-no-ssh v0.0.9-no-annotate-no-ssh [14:28:10] (0):~/src/github.com/my/repo % git -c log.showSignature=false tag -l --format='%(contents:body)' v0.0.9-no-annotate-no-ssh ``` Please review the rest of the bug report below.
