MPS issue job003751

TitleMVFF debug does not work with large objects
Assigned userGareth Rees
DescriptionThere's a comment in mpmss.c [1], "IWBN to test MVFFDebug, but the MPS doesn't support debugging cross-segment allocation (possibly MVFF ought not to)." and sure enough, if you try, then you get the assertion:

    dbgpool.c:357: MPS ASSERTION FAILED: limit <= SegLimit(seg)
AnalysisfreeCheck is only prepared to expose and cover one segment. But it would surely be possible to loop over all the segments in the range.
