Bug#803109: gcc-5: If compiled with gcc-5, GnuPG classic cannot import certain public keys
Package: gcc-5
Version: 5.2.1-22
Severity: normal
Tags: upstream
Dear Maintainer,
I noticed that on Debian testing, I cannot import a certain public key into
gnupg-1.4.19 that I can import on Debian stable. This is how the bug is
triggered:
$ gpg --recv-key 67F41449
gpg: requesting key 67F41449 from hkp server keys.gnupg.net
gpg: DBG: armor-keys-failed (KEY 0x67F41449 BEGIN
) ->0
gpg: DBG: armor-keys-failed (KEY 0x67F41449 END
) ->0
gpg: assuming bad signature from key 67F41449 due to an unknown critical bit
gpg: assuming bad signature from key 67F41449 due to an unknown critical bit
gpg: key 67F41449: no valid user IDs
gpg: this may be caused by a missing self-signature
gpg: Total number processed: 1
gpg: w/o user IDs: 1
$ gpg --list-key 67F41449
gpg: error reading key: public key not found
When I compiled vanilla versions of recent GnuPG classic releases, noting changed.
Only after I did `./configure CC=gcc-4.9`, the key could be imported:
$ gpg --recv-key 67F41449
gpg: requesting key 67F41449 from hkp server keys.gnupg.net
gpg: DBG: armor-keys-failed (KEY 0x67F41449 BEGIN
) ->0
gpg: DBG: armor-keys-failed (KEY 0x67F41449 END
) ->0
gpg: key 67F41449: public key "Xxx Yyy <xxx.yyy@zzz.invalid>" imported
gpg: Total number processed: 1
gpg: imported: 1 (RSA: 1)
$ gpg --list-key 67F41449 >/dev/null && echo works
works
GnuPG's test suite currently does not catch this bug, i.e. `make check`
succeeds in any case.
