I had this error (WIN32 build, but the build process is the same 
according to https://openssl.org/docs/fips/UserGuide-2.0.pdf) when my 
FIPS-capable OpenSSL was broken.  Although compilation phase reported 
success, the built-in FIPS tests failed.  Obviously stunnel was also 
unable to initialize FIPS mode.

What this error means is that in-memory image of the FIPS module was 
found to be different from the one acquired during the original build.  
In my case the problem was caused by the linker enabling ASLR by 
default.  Downgrading the compiler suite fixed the problem without 
violating FIPS policy 
as ASLR is disabled in older linkers by default.
