Comment (by shlevy):

 D4388 fixes some of this, by removing non-determinism in cost centre
 symbol names (which caused linking errors when doing distributed builds
 with nix). A unique was replaced with a 0-based index that increments in
 source location order for a given module, cost centre name, and cost
 centre type.
