The changes of2144ca38d2(Get rid of CppUnit boilerplate in DynamicLibraryTestCase, 2022-04-17) accidentally undid the workaround from054cb35b39(Workaround for a crash with gcc 9.1 from MSYS2 MinGW 32bit, 2019-08-03), so work around the same problem again by avoiding using CHECK() with function pointers.
