+Subject: [PATCH] feat: Unsafe transmute for PDB symbols (#258)
+
+This works around compilation errors on nightly when casting to the
+generic `DynIterator` type. This is caused by invariant lifetimes on
+PDB's stream type. The transmute is actually safe since the lifetime of
+the data is proved to be larger than the lifetime of the derived object.
