C1 generated code encodes a compressed oop into to temp register before it stores it. In case of patching, a GC may happen and the compressed oop may be incorrect when it is stored to memory.
I should have acknowledged that all the credit for this bug (investigation and fix) goes to Mikael Gerdin and Erik Helin from the GC team. Thanks to them!
Roland.
