--- Comment #4 from Jürgen Reuter <juergen.reuter at desy dot de> --- Here is our full test suite: http://www.desy.de/~reuter/whizard_gfortran-170126-1131.tar.gz Just unpack, do make, then it will produce two binaries, rt_error and rt_error2. The first one has ca. 60 tests implemented of the form ./rt_error --check <name_of_test> You find a list of them in the file main_ut.f90 in the last select case. the second binary can be run as ./rt_error empty.sin I suspect that all of these are the same error, but wanted to provide the information for you guys. Now, I'll try to reduce the first test case.
