Description Don Wellington 2001-08-03 18:27:09 UTC 
When FOP attempts to render a large external graphic, it appears to enter an
infinite loop in the "Formatting FOs into areas" stage.  It outputs area numbers
until it runs out of memory.  Shrinking the offending file fixes the problem. 
The limit appears to be the size of the area available on the page.

This bug persists in 0.20.4rc. I include the smallest example that I can come up
with. space-before.optimum="1pt" in the surrounding fo:block seems to be needed
to trigger the infinite loop

The patch supplied to resolve bug 8778 resolves this bug as well, halting the 
infinite loop after a sufficiently large number of attempts at layout.
