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

or that libgcrypt caused on Windows at one point:

	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.
