jpeg plugin crash in WIN64

Hi, I think I've got a good clue: the problem is jump_buf alignment (must be multiple of 16). https://github.com/OpenSmalltalk/opensmalltalk-vm/issues/119

Great to see this progress. Thanks Eliot. Just curious about the strategy of handling pinned objects during Image save/load. Could the pinned memory possibly be considered to have been invalidated much like when the VM exits? And thus the VM could move and compress the pinned objects at some point, or automatically unpin all objects in a saved Image? Or are their cases where the pin is useful to persist across saves? Maybe if an external library relies on one pinned object refering to the memory location of another pinned in some domain document structure? Thus it is Image's responsibility to unpin all objects to minimise Image size? I guess unpinning by the Image would be best at Image load rather when saving since the Image may continue. cheers -ben

It is now ready for prime time. SpurPlanningCompactor is a three-finger algorithm that slides objects down to the first finger, which points at the first free object, from the first unpinned, marked object, while stepping around intervening pinned objects pointed at by the third finger. StackInterpreter: Fix serious and ancient bug with stack checking and event checking. The event check piggy backs off the stack check, but the old code would not handle a stack overflow if there was an overflow and an event check at one and the same time, allowing frames to grow down the stack page in cases where there are lots of events (such as profiling). Fix assert fails in Spur due to failing perform primitives not restoring the function pointer and argumentCount correctly. Cogit: Fix checking the lists of cog methods (openPICList and unpairedMethodList) when compacting the method zone. Fix a bug with freeing a method that might have either a newxtMethod or an IRC. Must not free CogMethods. Fix a couple of C compilation warnings.Have printCogMethods print totals of the number of methods & PICs in the code zone. Fix a slip in printCogMethodsWithPrimitive:. Spur: provide isUnmarked: for debugging with printOopsSuchThat:. remember the first unmarked object found by allObjectsUnmarked in the bogon var, and keep hold on to it via printBogons so it is not deleted by the C optimizer.
