Anyway the CR macro stands for Containment Record. Usually you have a pointer into a structure and you use the CR macro to find the start of the structure. It is common for things CR to include a signature at the start of the structure. The ASSERT you are almost reporting is likely some kind of data corruption. Like buffer overflow, use after free, etc. But without line number info it is hard to say which one it is.
