Ok, I can reproduce this with v6 of the patch:
expecting success:
test_must_fail git merge --ff-only --verify-signatures side-untrusted
2>mergeerror &&
test_i18ngrep "has a good, untrusted GPG signature" mergeerror
==1430== Conditional jump or move depends on uninitialised value(s)
==1430== at 0x4C26B5C: strchrnul (mc_replace_strmem.c:711)
==1430== by 0x47B90B: check_commit_signature (commit.c:1057)
==1430== by 0x444212: cmd_merge (merge.c:1245)
==1430== by 0x4050E6: handle_internal_command (git.c:281)
==1430== by 0x40530C: main (git.c:489)
Though I also can't see the problem. strchrnul gets passed a char* that is just
fine.
