###!!! ASSERTION: After-spacing inside a ligature!: 'i - 1 <= aStart || aSpacing[i - 1 - aStart].mAfter == 0', file /builds/slave/mozilla-central-macosx-debug/build/gfx/thebes/src/gfxFont.cpp, line 2757

I think this is a recent regression.

er, only happens with gfx.font_rendering.harfbuzz.level set to 1.

Sorry, the keys are like right next to each other.

Hmm, it's probably got something to do with how the harfbuzz back-end treats the "stray" combining mark without a base character; probably confuses our clustering. I'll look into it.
At least with harfbuzz we actually display the diacritic..... if I set harfbuzz.level to 0, it disappears from the output completely.
Summary: "ASSERTION: After-spacing inside a ligature!" → "ASSERTION: After-spacing inside a ligature!" with harfbuzz enabled
WFM on trunk.

By the way, the pref was removed in bug 1018034 after defaulting to 255 for a while.
