SUGGESTED FIX http://analemma.sfbay.sun.com/net/prt-archiver.sfbay/data/archived_workspaces/1.5/tiger_update9_baseline/2006/20060629135956.kbr.tiger_update_baseline/workspace/webrevs/webrev-2006.06.29/index.html

EVALUATION Suggested fix by ###@###.### and ###@###.### restricts register masks for values that can show up in debug info for compiles of native wrappers and stubs so they are not allocated into registers.

EVALUATION The problem appears to be in the debug information generated for synchronized native methods. The receiver is reported as being in edx but the RegisterMap doesn't have a valid on-stack location for that register since we're in a compiled native wrapper and there's no runtime stub above this frame. The attached test case reproduces the problem; still working on a fix.
