This is based off of my real mini-app that uses a 2D Coarray (could be simplified of course).  For this example, the 2D's are square (meaning the number of indexes is the same).  The directory structure contains the program (prog.f90), a template PBS script (coa.pbs), and a controlling compile/execute command (go.csh).  The output is contained in sub-directories labeled 4-11.  Each directory contains the submitted PBS script (coa.pbs) and the output log (output.log).  For 4-8, the output is as expected - it finishes successfully.  For 9-11, it just blows up.  No error given.\r\n\r\nSame executable with just differing input.\r\n\r\nNot to rub it in, but these work perfectly for all input under Intel 2019.1.144.\r\n"}}
