Mikael, could you put in a pre-processed testcase for folks to look at reproducing with a cross rather than reproducing this with a full bootstrap ? Eyeballing the pattern doesn't show anything obviously wrong in the constraints so this may well be an LRA issue. ^ permalink raw reply [flat|nested] 7+ messages in thread
