the MiscPrimitivesPlugin loop when generating.
the cause is :
the primitives: #findSubstring:in:startingAt:matchTable: was change to the primitive that name is now: #findSubstringViaPrimitive:in:startingAt: matchTable:
i can simply change the name in #translatedPrimitives (MiscPrimitivePlugin ) method but i am looking for long term solution.
