Memory error using BUILD_SHARED_LIBS=ON for both gtest,gmock and C++ test program

[dswel...@gmail.com]

I wanted to build my test with BUILD_SHARED_LIBS=ON, since one of my files to be tested involved a .so files.  I thought I had to build gtest,gmock also as .so files, so I built them with -DBUILD_SHARED_LIBS=ON option.  Then I created a CMakeLists.txt  for my test_shared.cpp file with the BUILD_SHARED_LIBS option on.  In the CMakeLists.txt file I added "add_custom_command" to run the test after building it.  But when it ran it resulted in a memory error in the output as shown below in directory "/home/welchons/test/use_gtest_with_build_shared_libs" with subdirectory "build" where the cmake and make are done.   I have attached a much-simplified source file, test_shared.cpp (basically an empty file with "TEST(){}" , and the CMakeLists.txt file just to show the error more clearly.
