 Are you positive that it is really stuck inside the libgcrypt function,
 and that the problem is not that the function is called over and over?

 Can you work with gdb when it gets stuck? Step through? What does it
 actually do in that function? Also, it would be helpful to build a
 libgcrypt which includes debugging symbols.

 If it really does get stuck inside libgcrypt then maybe the problem isn't
 actually with libssh2. (Though it could also be a problem in libssh2 that
 gives libgcrypt bogus data and causes it to run off and do something
 silly.)
