Hi Mark,
There is something in the dllcc interface that goes wrong. The
translation of a string argument (collection) goes wrong in the vm. If
you use "interface cCrc32: crc buffer: collection fixedHeapAddress
length: position" everywhere it is called it works fine.
There will be a more elaborate post coming soon because flushing the
stream will break it for further use.
Regards,
Cham
