Tinc 1.1pre3, 1.1pre4 hangs after some time, on win32 platform

[Nick Hibma]

>> Recently I ran into some problems when trying to test the new tinc 1.1 builds under windows. The main problem is that the tincd daemon randomly hangs (usually in first 1-3 minutes after start). Sometimes it happens quietly, and the log does not display anything. But from time to time, there are bunch of decryption errors ("Error while decrypting: error:06065064:digital envelope routines..") before the actual hanging.

We have old versions in the field and upgrading is not really an option. I've seen stalled tinc connections (well, I think it was tinc hanging, but no way to verify, no way to reproduce, and lots of other bugs in our rubbish). Which versions does this bug occur in? All versions up to now?
