<div dir="ltr">Dear all,
<div><br>
</div>
<div>My colleague found a bug in Metapost 1.803 which I would lile to report. In the following minimal example, showdependencies shows something inappropriate, which gives "This can't happen (dep)" error later. But if I move the third s-relation after setting
z[4,6,8], everything works fine.</div>
