When encountering a WHILE loop inside CCTK_ANALYSIS, Cactus simply hangs.
I have created a simple thorn, ScheduleTester, that reproduces this problem 100% of the time. The thorn only takes as input the number of iterations desired in the WHILE loop. I have attached this thorn, as well as example .par and ThornList files to this ticket.
This problem is verified to exist within 2015_05 as well as 2014_11 ET releases. I have not tried past releases.
