Hi
I have code below for the SHA256 implementation it compiles and works fine
in *Debug* but when switched to *Release* configuration it fails with
following message:
Exception thrown at 0x4296339C (cryptopp.dll) in CryptoppCPP.exe:
> 0xC0000005: Access violation reading location 0x6F57206F.
> If there is a handler for this exception, the program may be safely
> continued.

Does anyone came across this issue before? How can I track what could be
causing this issue?
Thank you.
