I will look into it once my debug builds compiles...
Comment 2 User image Bernd 2011-07-31 10:53:28 PDT
I see it in my debug build.

reduced testcase

the structure now  avoids table pseudo frame creation.
Its important that thead is not the first child of the table
Comment 4 User image Bernd 2011-08-03 22:07:15 PDT
what happens here is that on the first page

tbody splits at the available space and creates a next inflow
the table puts the nif on its overflow list.

the table height computation reports a slightly larger desired size (2 px) than available so the table gets marked as truncated

and gets pushed entirely on to second page

then the same table frame is reflowed and gets back the frame from the overflow list

now the mFrames are

tfoot > tbody > thead > tbody_nif 

where > stands for next sibling relation ship

this fixes the crash but does not fix the problem with the tfoots that are not placed due to size constraints.

The problem comes here from the fact that a repeatable tfoot can't be placed. If it is not pushed it will cause in CalcDesiredHeight a increase by one cellspacing and misplaced tfoot on the page where it does not fit.

Boris, we compute the repeatability of tfoot as a quarter of the page size, however we are not guaranteed that the tfoot will fit. The patch here says if it does not fit then we remove the repeatability and push the tfoot to the next inflow. Otherwise tfoot will end as a not placed frame at 0,0 relative to the table and spoil nsTableFrame::CalcDesiredHeight at by addinga 0 height and one cellspacing in excess. 

I will push this over to try, once my commit is reenabled  (bug  677040)

Comment 10 User image Bernd 2011-08-09 12:33:58 PDT shows a consistent failure pattern in crashtests

REFTEST TEST-UNEXPECTED-FAIL | file:///c:/talos-slave/test/build/reftest/tests/layout/tables/crashtests/576890-2.html | assertion count 12 is more than expected 0 assertions
REFTEST TEST-UNEXPECTED-FAIL | file:///c:/talos-slave/test/build/reftest/tests/layout/tables/crashtests/576890-3.html | assertion count 2 is more than expected 0 assertions

==> more work required
Comment 11 User image Bernd 2011-08-09 12:41:23 PDT
more work is means bug 610245
Comment 12 User image Bernd 2011-08-13 10:31:02 PDT pushed together with the patch for bug 678447, when pushing this to aurora or beta both patches are required otherwise crash tests will go orange.
