Good! That means that libgcrypt won't cause this sort of problem that OpenSSL causes:
https://mta.openssl.org/pipermail/openssl-users/2015-January/000295.html

https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=3270
I remember some issue such as this coming up somewhere in Wireshark, but it might have been bug 3270.
