STR-135, martin:
This is not a minor issue.

STR-135, martin:
Btw, I’m not really into the impelementation of the redefinition detection, but this issue might also be caused by dead code elimination of the strategies that are not invoked. If so, then the check should be move somewhat more to the front of the compiler pipeline
