As most C/C++ libraries, an object is not thread-safe unless it is explicitly mentioned it is. This holds for OGRCoordinateTransformation. In GDAL 2.4 with PROJ 5.x, you might not notice severe issues in practice (beyond the PROJ error state being accessed concurrently). With PROJ 6, you'd likely get crashes.
