free(): invalid pointer at test exit

[arkadesOrg]

Can someone please give me a hint where the cause of this error may be located? I am using Boost 1.83.0

when I run my test manually I get:

Running 1 test case...

*** No errors detected
free(): invalid pointer
Aborted (core dumped)

here is the test source:

#define BOOST_TEST_MODULE MyTest
#include <boost/test/included/unit_test.hpp>

BOOST_AUTO_TEST_CASE( free_test_function )
/* Compare with void free_test_function() */
{
  BOOST_TEST( true /* test assertion */ );
}

The relevant valgrind memory analysis I got:

I build with cmake:

# Testing Framework
find_package(Boost REQUIRED COMPONENTS unit_test_framework)

add_executable(testcase_simple testcase_simple.cpp)
target_link_libraries(testcase_simple Boost::unit_test_framework)

enable_testing()

add_test(NAME TestcaseSimple COMMAND testcase_simple) 

Btw did I mention I use Arch? :)

Thank you!

[arkadesOrg]

With cmake I had to add the definition to use shared libraries for my specific use case:

set_target_properties(my_test PROPERTIES COMPILE_DEFINITIONS "BOOST_TEST_DYN_LINK")

Thanks for this awesome Boost framework!

[tranqui]

I get the same error, also on arch with boost 1.83.0. However, setting BOOST_TEST_DYN_LINK did not fix it in my case.

[arkadesOrg]

Did you also try to set up a very basic test case?

[tranqui]

Yes, mine was essentially identical to yours just with different filenames.

I also tried direct compilation with g++ -o unit_test unit_test.cc -lboost_unit_test_framework with the same memory leak. Here unit_test.cc could be your code snippet to reproduce the error.

[arkadesOrg]

I see, so you generelly link with cmake, but also tried to directly do it. Should'nt you have passed the -DBOOST_TEST_DYN_LINK defintion to g++?

PS: do you have a similar valgrind output?

[tranqui]

Ah, yeah I just manually placed the #define BOOST_TEST_DYN_LINK inside the cpp file for the manual compilation.

Yes re: similar valgrind output:

SUMMARY: AddressSanitizer: 102 byte(s) leaked in 5 allocation(s).

I suspect this is an arch linux problem rather than a boost problem.

I also tried to statically link the boost libraries, but got multiple definition linker errors.

[arkadesOrg]

#define BOOST_TEST_DYN_LINK is exactly what I tried also, but -DBOOST_TEST_DYN_LINK did the trick for some reason. I build on arch linux, and the testcases now exit properly.

[tranqui]

I have tried both to no avail.
