Comment(by strk):

 Failure for #350 is indeed the originally reported faiure. This is
 annoying. Are you sure you're building with -ffloat-store ? Could you
 retry that with r3338 or r3335 ? Or generally bisect to see if you got any
 success for it ?

 As per the #398 failure it does look like a minor coordinate drift. We're
 checking for exact equality (pointwise) which is the reason for the
 failure. Note that also JTS checks for pointwise equality, which is the
 reason why I've tried to track as closely as possible JTS as per
 operations precision, getting back from long doubles to single doubles...
