Re: [Ikvm-developers] 0.42.0.3 under mono

[Jeroen F. <je...@su...>]

Hi again,

Actually, looking at it some more, while ExceptionSorter is arguably broken, there is really no reason for Mono's Array.Sort() to call it with the same object as e1 and e2 (and that is the only case there Compare should ever return 0). So arguably this is a Mono bug (at the very least a perf issue).

Regards,
Jeroen
