GDB Backtrace for the GTK port when it crashes on fast/sub-pixel/compositing-layers-on-subpixel-position.html
On the GTK port this test also crashes sometimes. I have attached the backtrace of the core dump that I obtained by running the test in a loop until it crashed.
unskipped here: http://trac.webkit.org/changeset/174730
Reopening since this test still fails on the GTK port. I have retitled the bug to reflect that is specific to GTK.
On GTK, the diff is this one: https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/r174743%20%283510%29/fast/sub-pixel/compositing-layers-on-subpixel-position-diffs.html
