--- Comment #4 from mazhe@alkumuna.eu --- Ok, been quite overwhelmed by events, but I managed to take the time to check the results more closely: it's not quite an issue due to the platform.
I noticed that an assert was triggered in the freebsd version and not the linux one, in the js_copy function which use a pattern of having assert(0) if it encounter a unknown case after a switch block.
So I rebuilt wine with -DNDEBUG and got results similar to linux (even better, as I can actually use torrenting for updates).
Still somewhat of an issue if this assert is triggered, but I'm not sure there's much interest in fixing it, this issue can be closed if necessary.
