The falcon_pagesize2K and falcon_pagesize32K fail across all platforms with the following backtrace:

The failure does not appear to be page-size specific, it is just that those two tests cause it fairly consistently. The queries are just basic DML statements with no ALTER. Recovery appears to be successfull.

How to repeat:
Run falcon_pagesize32K with RQG.
