Created attachment 8727577 [details] testcase (crashes Firefox) Stack and testcase is somewhat similar to bug 866767, but this testcase doesn't use "filter: url()", which Mats identified as important in bug 866767 comment 3. ASan Opt Reports "stack-overflow". Fails to produce a stack trace, showing only a top frame unlucky enough to the stack barrier. Release opt Reports what looks like a stack overflow. Similarly fails to produce a stack trace. bp-884771c5-236a-4242-ba82-784e02160307 Debug Hangs due to hitting too many non-fatal assertions. The assertion failures have a repeating stack portion, so I assume this is the same repeating portion that eventually leads to a crash in non-debug builds. The repeating portion of the stack is: > #122: PresShell::ProcessReflowCommands(bool) [layout/base/nsPresShell.cpp:9125] > #123: PresShell::FlushPendingNotifications(mozilla::ChangesToFlush) [layout/base/nsPresShell.cpp:4069] > #124: PresShell::DidDoReflow(bool) [mfbt/RefPtr.h:296] > #125: PresShell::ProcessReflowCommands(bool) [layout/base/nsPresShell.cpp:9125]

This one doesn't use filters at all.
