+Subject: [PATCH] core: Fix use-after-free issue in test
+
+* tests/gpg/t-edit-sign.c (sign_key, verify_key_signature): New.
+(main): Factored out signing and verifying the result.
+--
+
+Factoring the two steps of the test into different functions fixes the
+use-after-free issue that was caused by accidentaly using a variable
+of the first step in the second step.
