TEST_HEADER

summary = test for non-bug with mark-sweep scanning in AWL
language = c

END_HEADER
I wrote this test with drj when we were convinced there was
a bug in pool scanning because of ScanStateSetSummary setting
unfixed to be potentially bigger than the segment summary. But
it turned out not to be a problem, 'cos ScanStateSetSummary is
called (at least by AWL) _before_ scanning is done.
