I am building a DLL that includes the OpenSSL FIPS object module. This is on Windows using Visual Studio 10.0. I have the 64-bit version working fine but when I build a 32-bit version, the "incore fingerprint" fails to match when I load the DLL and call FIPS_mode_set(1). I had the same problem with the 64-bit version at one point but then it seemed to just "fix itself" and I never saw the problem again.
While debugging the code, I found that when linking the DLL, the .text and .rodata values are: .text:5CC1B000+302160=5CC64C50 .rodata:5CCDA134+46364=5CCE5650 But when we load the DLL, the values are: .text:5C85B000+302160=5C8A4C50 .rodata:5C91A134+46364=5C925650 (Not always exactly this, but they never match the numbers above. The sizes are always correct.) We're calculating the signature on a different chunk of memory so obviously they will not match. The question is why are the pointers different? Graeme Perrow
