std::queue not changing size after push in test case

[syntactical]

Description

I'm writing a test that involves pushing items to a queue:

TEST_CASE( "strings are returned as-is", "[multi-file:2]" ){
    Parser parser;

    LettersGroupToken t("abcdef");

    std::queue<Token*> tokens;
    tokens.push(&t);

    std::vector<std::string> items = parser.parse(tokens);

    REQUIRE( items.size() == 1 );
    REQUIRE(items[0] == "abcdef" );
}

My issue is with tokens.push(&t);. It does not change the size of the queue tokens. After the push operation the size of tokens is zero. The same behavior happens when using emplace.

I've tried using a vector instead of a queue, and push_back works as intended, changing the size of the vector. I need to use a queue though...

Other things I've tried:

• Defining CATCH_CONFIG_MAIN in the same file as this test case - still seeing this error
• Defining CATCH_CONFIG_MAIN in another file - still seeing this error
• Removing [multi-file:2] tag - still seeing this error
• Changing to std::queue<int> - still seeing this error

BUT, moving this code to a main method of the program made the bug go away - the queue behaved as normal.

... really confused! :(

Extra information

This is the actual error I'm getting in the CLion test runner:

/fakepath/test/ParserTest.cpp:14: Failure:
fatal error
Process finished with exit code 132 (interrupted by signal 4: SIGILL)

• Operating System: macOS High Sierra
• IDE: CLion 2018.2.2
• Compiler+version: Whatever default C++ compiler used by XCode 9.4.1

Never mind-- this looks like it's a bug in CLion that makes it impossible to inspect certain containers when running tests.

Ok, thanks for reporting back.
