Non-Spur CogVM 3427 and 3410 cannot load PNG files anymore

marcel.taeumel
Hi Eliot! :)

ImageReadWriter formFromFielNamed: 'someform.png'

works with the Spur VM but not with the v3 one. The bug seems very strange. Build 3397 still works, 3410 and 3427 do not.

PNGReadWriter DNU #next:into:startingAt: called in PNGReadWriter >> #processNonInterlaced

However, z should be a ZLibReadStream and not "self" ... I suppose there is some bug with temps and stack frames? o.O

The message object, which is generated for the DNU, has the wrong lookup class. Hmpf...

Best,
Marcel

same if you use latest cog with Pharo, you can't even open world menu, because a compressed image fail to decompress...

and this does not happen with a stack.v3 vm, but only with a cog.v3 (assert, debug, fast whatever...)
