Versions with IF-clause or Final lead to compile objects with UNTIED tasks only

Health and nQueens sources leads to produce always executables with UNTIED tasks when compiling with IF-Clause or Final Cut-Off, even when executables with TIED tasks should be produced.

I generated some dump of the object files and indeed the "flag" parameter passed to function "GOMP_task" has always the UNTIED bit set in the aforementioned scenarios.

I mean, when using GCC compiler.
