Hi. I just tried running a parameter file with WeylScal4 using the ET_2023_11 release, and it fails during the pre-initial stage, with screen output like the following:

-------------

I tried to run the WeylScal4 testsuites too (Teukolsky etc), with the same "Assertion `current_function->RDWR' failed" message.

Just to check, I went back an ET release (ET_2023_05), and did the same test, and the tests ran & passed.

So did something happen between releases to change the behavior of WeylScal4? And would it affect other Kranc-generated thorns too?

Thanks, Bernard
