Since your initialization in respect to the threading system looks
correct, there are two possibilities:
1) the problem is indeed in Libgcrypt and thus you have found a new
2) the problem is not in Libgcrypt.
I cannot exclude the one or the other. You could try to do the
following: protect all calls into Libgcrypt by a shared lock; this
way, Libgcrypt would never be used by two threads at the same time.
If the problem keeps being reproducible, 1) should be excludable.
