Re: How do I use CallStack?

After staring at your bug confusedly for a few minutes, wondering why I couldn't simplify it, I realized that the actual warning I was getting was in *mkTcTransCo*, not rewriteEqEvidence. mkTcTransCo does not in fact use a CallStack (by default) so the redundant constraint warning there would be correct. If I add a call to error, everything seems to check out.

Can you confirm?

No. I had modified mkTcTransCo to print out the call-stack, so that wasn't the problem. If you can't reproduce quickly, I'll take another look at this when I get a chance. Thanks for taking a pass. Richard

Thanks! Eric
