Follow-up Comment #18, bug #63581 (project groff):

The reason it hangs is because there is an infinite loop. The infinite loop is
in the while statement in line 18123 when START is called for the second time
in the collated document. The reason it loops is because #DOC_LEAD has a zero
value on entry to the loop.

So I think this is only triggered for collated documents. I have not
investigated why #DOC_LEAD is set to zero sometime after the first document
completes and the second is STARTed, but not with postscript or pdf.
