Changing the
for (const innerValue of allowContentIter(mapped)) {
yield innerValue;
}
inner loop in Iterator.prototype.flatMap to
yield* allowContentIter(mapped);
then attempting to run the JS shell results in the following segfault:
Assertion failure: allowSelfHosted || emitterMode != BytecodeEmitter::SelfHosting (.close() on iterators is prohibited in self-hosted code because it can run user-modifiable iteration code), at /Users/avandolder/dev/mozilla-unified/js/src/frontend/BytecodeEmitter.cpp:2864
zsh: segmentation fault ~/dev/mozilla-unified/build_DBG.OBJ/dist/bin/js --enable-iterator-helpers
```.
