As reported on Pharo-users by Hilaire Fernandez,and affecting DrGeo. Reading PNG fails on 64-bit Spur due to denormalized large integer passed as parameter to a primitive. Fix is to normalize the integer.

Unit test and fix are in Squeak trunk repository http://source.squeak.org/trunk.

To reproduce: Unit test is PNGReadWriterTest>>testNewFromSampleBytes in GraphicsTests-dtl.44.

Fix is in Graphics-dtl.377. There are four methods that need updating:
PNGReadWriter>>copyPixelsRGB:
PNGReadWriter>>copyPixelsRGB:at:by:
PNGReadWriter>>copyPixelsRGBA:
PNGReadWriter>>copyPixelsRGBA:at:by:
Priority Priority: 5 – Fix If Time Status Status: Work Needed
Assigned To Assigned to: Everyone Milestone Milestone: Later
