Cmake Gtest project exe exits with errorcode 255 - c++

Question

I have been using a number of c++ projects for gtest unit cases. While all these were executing fine all these years, now after updating the openssl version 1.1.1a, seeing some strange problem. Bilt in VS2017
the test project exe is not executing or not starting at all. I tried executing the exe from a command prompt. It just comes out of the execution immediately without any execution or message. It is not taking or considering any argument like --shuffle-tests.
I tried adding trace cout logs in main function but still its has no effect.
The error i get is
6: Test command: plugin-tests.exe "--gtest_shuffle" "--gtest_output=xml:TESTS-plugin.xml"
6: Test timeout computed to be: 10000000
6/8 Test #6: plugin-tests ...........***Failed 0.01 sec
I am helpless in debugging in the gtest exe as there are no proper documentation for this as well.
Could any body please shed some light on this ?
It has the standard GTest functions to init and runn all tests. This has been working all these years.
The change i made in the code is,
Modified
EVP_CIPHER_CTX m_context_encrypt
to
EVP_CIPHER_CTX *m_context_encrypt
and did
m_context_encrypt = EVP_CIPHER_CTX_new()
as per the structure changes in openssl1.1 onwards.
And, the openssl is statically linked to the project exe which required two of the windows libraries to be linked with
crypt32 ws2_32
so added those dependency the cmake like,
if( WIN32 )
target_link_libraries(${PROJECT_NAME} crypt32 ws2_32)
endif()
The gtest unit test cases are executing successfully in linux build.
The problem is with the windows execution.
However out of 8 test projects, one test project is able to execute properly in windows, and i find no difference in the cmake files.
It is kindof strange
Note: Exit code of the exe seems to be 255
