The stderr output is
```
Loading with T9693_initial.hs
T9693_main.hs:4:1:
Same exact name in multiple name-spaces:
type constructor or class ‘X’, declared at: T9693_main.hs:4:1
data constructor ‘X’, declared at: T9693_main.hs:4:1
Probable cause: you bound a unique Template Haskell name (NameU),
perhaps via newName, in different name-spaces.
If that's it, then -ddump-splices might be useful
Reloading with T9693_modified.hs
T9693_main.hs:1:1:
Data constructor ‘X’ used as a type constructor
```
The strange thing is that the modified version uses (mkName "X"), which should
be fine for simultaneous use in both a data constructor and type constructor.
Indeed, on a fresh load, the modified version works fine. So there is some sort
of state left over from the prior load when (newName "X") was used.
