I was running with VM 3.6-3 found an address alignment error in the
JPEGReadWriter2 plugin, which Ian Piumarta diagnosed as:

	This looks like a problem with the plugin code failing to respect the 
	minimum alignment restrictions on the "cinfo" structure (which would be

	8-byte alignment on Sparc for the 'double' members).  A cursory look at

	the Squeak glue for the plugin reveals that the space for the struct is

	allocated in a ByteArray, which would only guarantee 4-byte alignment 
	(and would move it around with GC, meaning padding could not be used to

	guarantee minimum 8-byte alignment either).

	The only way to fix this properly for Sparc would be for the plugin 
	author to copy the info structure out of the ByteArray into a local 
	buffer before passing it to the jpeglib routines (and copy it back into

	the byte array if/when it's modified).

Is the author of JPEGReadWriter2Plugin around to fix this?
