[stunnel-users] centos 6 - stunnel 4.42 unusable (libssl trap divide error) in FIPS mode (default)

[draeath]

I just finished building and configuring stunnel 4.42 on my x86_64
CentOS6 box. It appears to run, but not long into the SSL connection
stunnel dies. Log info below.

This only happens if I do NOT specify --disable-fips during
./configure (as it enables FIPS by default). I assume this is because
FIPS compliancy requires a key to have a passphrase, which my key does
not have?
