Update: This doesn’t seem to have anything to do with MKL. Just linking with all the boost libraries is enough to cause this. I was able to repro this with just a few files. I am fairly certain this is because of some issue with linking incorrect libraries. Please let me know. I realize that I don’t need all these libraries for the simple test cases I have written. My g++ version is 4.4.6 Boost version 1.63

Hi, Sorry for not replying earlier, I haven't seen the message. Problem with your code is that you are using the included and the shared library version: * included: http://www.boost.org/doc/libs/1_63_0/libs/test/doc/html/boost_test/usage_var... * shared lib version: http://www.boost.org/doc/libs/1_63_0/libs/test/doc/html/boost_test/usage_var... See below for inline comments. Solution: * remove the single header variant * make the BOOST_ALL_DYN_LINK visible to all compilation units (global defines) Hope this helps, Raffi

File1: // cat mklmain.cpp

#define BOOST_ALL_DYN_LINK

//Raffi: indicates shared lib version (for all boost)

#define BOOST_TEST_MAIN //Raffi: indicates this unit test will contain the main entry point #include //Raffi: this is the "included/one header" variant

File2: // cat mkl1.cpp

#include //Raffi: this is the static/shared library variant, but this does maybe not see the BOOST_ALL_DYN_LINK from the other cpp units

#include "logging-helper.h"

BOOST_FIXTURE_TEST_SUITE(mkltest1, Fixture)

BOOST_AUTO_TEST_CASE(math_test_functions1) { BOOST_LOG_SEV(lg, trace) << "Starting test case for mkl test 1"; float dot = 3; BOOST_TEST(dot == 3); BOOST_LOG_SEV(lg, trace) << "Ending test case for mkl test 1"; }

BOOST_AUTO_TEST_SUITE_END()

File3: // cat mkl2.cpp

#include // Raffi: same remark as mkl1.cpp #include "logging-helper.h"

BOOST_FIXTURE_TEST_SUITE(mkltest2, Fixture)

BOOST_AUTO_TEST_CASE(math_test_functions2) { BOOST_LOG_SEV(lg, trace) << "Starting test case for mkl test 2"; float dot = 3; BOOST_TEST(dot == 3); BOOST_LOG_SEV(lg, trace) << "Ending test case for mkl test 2"; }

BOOST_AUTO_TEST_SUITE_END()

File4: // cat logging-helper.h // I realize that not all these headers are necessary. Was trying out different things.

#pragma once #define BOOST_LOG_DYN_LINK 1 #include #include #include #include #include #include #include #include #include #include #include

namespace logging = boost::log; namespace src = boost::log::sources; namespace sinks = boost::log::sinks; namespace keywords = boost::log::keywords; using namespace logging::trivial;

class Fixture { public: src::severity_logger lg;

Fixture(){

logging::core::get()->remove_all_sinks();

logging::add_console_log ( std::cout, keywords::format = "[%TimeStamp%]: %Message%" );

logging::add_common_attributes(); } };

Hi, I recently wrote some tests using the Boost testing framework and everything was working fine until I used the intel MKL with my project. As soon as I started linking these libraries, the tests started failing with a segmentation fault. This happens after the test execution is done and when the cleanup is happening. Looking at what valgrind outputs, it seems like there is some memory being released which is invalid(not sure if it is because of calling free on already freed memory). This actually happens even if none of the code depends on the MKL. Just adding them to the linked libraries is enough to cause this.

I am not sure why this is happening. Are there any known compatibility issues between MKL and Boost testing framework. I was using ACML before this and the tests were working fine with them.

Thanks, Anand
