Compiler Crash on record interaction with iterable/spread operator and for loop

[AngryVelociraptor]

When attempting to compile the following code, the dart compiler crashes.
This was reproduced on dartpad on Dart version 3.0.5 and 3.12.0

final t = {
  ...<String, String>{}.entries.map<(String, String)>((e) => (e.key, e.value))
};

compiles() {
  for (final (var1, var2) in t) {}
}

doesntCompile() async {
  for (final (var1, var2) in {
    ...<String, String>{}.entries.map<(String, String)>((e) => (e.key, e.value))
  }) {}
}

void main() {}

Observe that if you comment out the function doesntCompile, the code that should be equivalent successfully compiles.
