running the test_runner crashes

[ranj14]

Hi.

I recently built the cpprestsdk project on linux-cent0S. I have these prerequisites available on my PC: Boost1.63.0, openssl1.0.1 and gcc485.

I ran cmake with -D options as :

cmake .. -DCMAKE_BUILD_TYPE=Release -DBoost_NO_BOOST_CMAKE=TRUE -DBoost_NO_SYSTEM_PATHS=TRUE -DBOOST_ROOT:PATHNAME=/boost_1_63_0/ -DBOOST_LIBRARYDIR:FILEPATH=/boost_1_63_0/libs/ -DBoost_INCLUDE_DIR:FILEPATH=boost_1_63_0/

When I run the test binary, it crashses.
./test_runner _test.so
** segmentation fault*

Could any one let em know what could be the issue here. Thanks

What did running it in gdb tell you? GR

@grahamreeds I ran into same problem on fedora 25. Following stack traces of segmentation faults are produced using GDB. Seems like a problem with boost library.

[ras0219-msft]

@saqibahmed515 It looks like all your call stacks are in the initial load of the test modules. This is extremely early on in the testing harness and isn't a failure inside the main cpprest codebase itself.

Just guessing based on the failure, but you probably have a toolchain problem between cpprest, boost, and your crt. Try writing a simple application that runs the code in [1]. It should crash in the exact same way.

[1] https://github.com/Microsoft/cpprestsdk/blob/master/Release/tests/common/TestRunner/test_runner.cpp#L72

std::vector<std::string> files;
using namespace boost::filesystem;
auto exe_directory = initial_path().string();
for (auto it = directory_iterator(path(exe_directory)); it != directory_iterator(); ++it)
{
    if (is_regular_file(*it))
    {
        files.push_back(it->path().filename().string());
    }
}

@ras0219-msft You suspected the right culprit. I tested the program you wrote and it gives following call stack at segmentation fault which is exactly same as previous stack traces:

Problem's been identified. It's my toolchains. Question is, what to do now. How can I work around the problem.
