This seems to be another case of #122024. The example code is a lot more complicated and I wasn't able to reduce it to a single file. I can delete a fair amount of code, but deleting the [switch case for `type(TestCase)`](https://github.com/Goddard-Fortran-Ecosystem/pFUnit/blob/cbe21b95eff70804acfd7f5a9b68dec291781c4a/src/funit/core/TestSuite.F90#L164). Allows this file to compile and then gets stuck on the next file with the same error.
```
