Please try passing NULL instead. The assembler should not depend on the isolate
when given a buffer. If it still does, let's fixit it.

   // Generated code is put into a fixed, unmovable, buffer, and not into
   // the V8 heap. We can't, and don't, refer to any relocatable addresses
   // (e.g. the JavaScript nan-object).
