resident compiler chokes on NSC |
| code |
see NSC
Note in symtab/AnnotationInfos.scala:
private object symbolReifier extends SymbolReifier {
val symbols: AnnotationInfos.this.type = AnnotationInfos.this
}
Crash will go away if we change symbolReifier to a value.

| what expected |
I can't seem to narrow this down. The code seems to depend on the entire compiler, and the crash doesn't occur if I isolate to just the three core files involved (AnnotationInfos.scala, SymbolTable.scala and SymbolReifier.scala). I'm pretty sure it has something to do with the symbolReifier object in AnnotationInfos, because changing it to a val avoids the crash.
