"ASSERTION: didn't subtract all that we added"
###!!! ASSERTION: program error: 'iter.IsLeftMostTable() || iter.IsRightMostTable()', file /Users/jruderman/central/layout/tables/nsTableFrame.cpp, line 6838
the assert from the bug title is gone the hang is not.
the hang comes from the dash drawing routine: <table width="33554432px" style="border-collapse: collapse;"><tbody style="border: 2px dotted yellow;"> means we will draw 4011103 small rectangles at http://mxr.mozilla.org/mozilla-central/source/layout/base/nsCSSRendering.cpp#2955
Summary: [BC] ASSERTION: program error: 'iter.IsLeftMostTable() || iter.IsRightMostTable()' → Hang [@ nsCSSRendering::DrawTableBorderSegment]
Still very slow but I wouldn't call it hang. Tested on Linux and OSX. Unlikely to affect any real web sites much though.
Testcase still asserts on trunk, now with: ###!!! ASSERTION: didn't subtract all that we added: '(space == 0 || space == nscoord_MAX) && ((l2t == FLEX_PCT_LARGE) ? (-0.001f < basis.f && basis.f < 0.001f) : (basis.c == 0 || basis.c == nscoord_MAX))', file /builds/slave/try-l64-d-00000000000000000000/build/src/layout/tables/BasicTableLayoutStrategy.cpp, line 1074 No hangs, though.
Summary: Hang [@ nsCSSRendering::DrawTableBorderSegment] → "ASSERTION: didn't subtract all that we added"
