Thanks for the report. Just build your example and...
```
$ GNUTLS_DEBUG_LEVEL=9 ./x
gnutls[2]: Enabled GnuTLS 3.6.5 logging...
gnutls[2]: getrandom random generator was detected
gnutls[2]: Intel SSSE3 was detected
gnutls[2]: Intel AES accelerator was detected
gnutls[2]: Intel GCM accelerator (AVX) was detected
gnutls[2]: unable to access: /etc/gnutls/default-priorities: 2
gnutls[2]: signatureAlgorithm.algorithm differs from tbsCertificate.signature.algorithm: 1.2.840.113549.1.1.5, 1.2.840.113549.1.1.12

gnutls[3]: ASSERT: verify-high2.c[gnutls_x509_trust_list_add_trust_mem]:92
GnuTLS processed -43 roots
```

Looks like GnuTLS is too pedantic for this cert: `signatureAlgorithm.algorithm differs from tbsCertificate.signature.algorithm`.
