>The type you pass to GlobalVariable's constructor for that variable

<div>for. Then the GlobalVariable itself will be a Constant of type "[10 x</div>
<div>%struct.dlist]*".</div>
<div><br>
</div>
<div>Yes, I verified that this is the case.</div>
<div><br>
</div>
<div>I enabled assertions and the error seems to occur while creating <i>GlobalVariable</i> for both struct dhash and struct dlist.
