Rickard, I think it looks good (not a Reviewer).

The problem in this crash was that we were given an incorrect fp (in this case 0x0) and had a pc that matched the C -> Java entry frame. The code then dereferenced fp +- offset. This change verifies that the fp +- offset is actually on the stack of the thread before doing the derefencing. Webrev: http://cr.openjdk.java.net/~rbackman/8016131/ Thanks /R
