False positive for pointer dereference when using doctest macro

SonarQube Server / Community Build
1

Must-share information (formatted with Markdown):

  • SonarQube Server
  • linux server on redhat 8
  • write a unit test in c++
  • write a unit test using doctest’s macro REQUIRE_MESSAGE

Do not share screenshots of logs – share the text itself (bonus points for being well-formatted)!

In a unit test, using the doctest library, in this block of code:

    REQUIRE_MESSAGE((pool != nullptr), "Pool is null");

    Converter converter;

    const auto a = converter.build(*pool);

Sonarqube raises this error at the call to build(*pool):
cpp:S2259 Forming reference to null pointer

It doesn’t expand the doctest macro REQUIRE_MESSAGE which checks if pool is nullptr.

Hello Ann,

We use enterprise edition 9.9.5. There is a plan to migrate to v10 later this year

Hi,

Your version is past EOL. You should update to either the latest version or the current LTA (long-term active version) at your earliest convenience. Your update path is:

9.9.5 → 2025.1.4 → 2026.1

You may find these resources helpful:

If you have questions about upgrading, feel free to open a new thread for that here.

If your error persists after update, please come back to us.
