I'm using stunnel in client mode on a Windows 7 x64 workstation, installed
using ftp://ftp.stunnel.org/stunnel/stunnel-4.52-installer.exe

Everything works until I try to check the server certificate for revocation
using an OCSP server, at which point stunnel crashes whenever I make a

The following error pops up in a dialog box: OPENSSL_Uplink(0FBE5000,14):
no OPENSSL_Applink

My config is pretty simple:

debug = 7
# I do want FIPS enabled, but I figured one problem at a time.
fips = no
CAfile = ca-bundle.crt
verify = 2
OCSP = http://ocsp.test.net/
options = NO_SSLv2

client = yes
accept =
connect = web.test.net:443

The log gets as far as:
2012.03.02 11:07:41 LOG7[4296:5008]: OCSP: server connected
when it crashes.
