What to you mean by that ? As indicated by the name, the function compute a transversal of an equivalence relation (the j-relation) so the choice is not canonical at all. It actually depends on the implementation of Cayley graphs. Please see #8445 which should fix this issue. > The only long term solution I see is a continuous build bot that runs on a > Solaris box (among others) and bounces tickets that fail.

I mean, neither authors of patches nor reviewers have the time/will/possibility to check on all the possible architectures. This should be automated. My dream solution (and I can tell you I'm not the only one dreaming about that) is the following: When you put a ticket on trac, you must clearly indicate in a field (not in the text) which patches should be applied in which order. A sensible default may be helpful here. You must also indicate on which other tickets this patch depend. Then in a fully automated manner a few time after, either: - a green light turn on indicating that all tests passed on all the architecture. - a red light turn on with a link to the log of the failure. Note that I've no idea how hard it is to implement in trac, neither if we have the necessary hardware to support this load.
