[Swftools-common] PDF2SWF - PDF Hangs and CPU maxed

[Matthew Richer]

We are attempting to use PDF2SWF for a particular PDF and we are running into an issue where the PDF processing just hangs and the CPU is spike @ 100% (50% on dual-core).  The point where it bottlenecks depends on the zoom factor.  At zoom factor 100 it stops at one point and at zoom factor 72 (default) it stops further on. 

 

I can make the file available for download if required.

 

Here is the tail end of my verbose logging:

Any kind of insight would be grateful.
