Description:
When running falcon_bug_22165 I have seen the following assert several times when running against Falcon checked out from the mysql-6.0-falcon-team branch:
Error: assertion (page->pageType == PAGE_sections || page->pageType == 0) failed at line 198 in file Section.cpp
The call stack from the crash is:

Information about what the page object:
(dbx) print -r *page
*page = {
SectionPage::Page::pageType = 4
SectionPage::Page::checksum = 0
SectionPage::Page::pageNumber = 4
SectionPage::Page::pageUnused = 0
SectionPage::section = 4
SectionPage::sequence = 0
SectionPage::level = 103
SectionPage::flags = 0
SectionPage::pages = (5)
}
How to repeat:
Run falcon_bug_22165 repeatably (probably on a multi-CPU machine).
Suggested fix:
No idea.
