> Address of  "C array" passed to releasePrimitiveArrayCritical() in line 211 in GDIBlitter.cpp
differs from address returned by getPrimitiveArrayCritical() call in line 202 for the same
array("matrix"). This sometimes causes debug VM crash with "debug error" messagebox. The problem
can be easily reproduced on VM with no support for pinning...
