Yes, I couldn't reproduce the issue without OpenMP.

It uses `Fortran::lower::genDeclareSymbol()` to declare privatized variables, but the typeparam of the original declare is lost for `character(<variable>)` types.
This is usually not a problem, since the length can be read from the corresponding box, but `allocate` clears it.
