Infinite loop bug on push/pull
-
I believe I have found a bug. While attempting a push/pull on a complex shape, the application entered an infinite loop, taking nearly 50% of the CPU time. I am running an older Toshiba Satellite laptop with recently updated Windows XP. Breaking in with MS Studio 2008 only let me confirm that memory is constantly being allocated and freed. Using MS Process Explorer, I took the following snapshots of the process…
