Summary0000933: Too much italic correction in unicode-math
DescriptionWhen using `unicode-math` in LuaTeX version 0.80.0 (TeX Live 2015 pretest), too much italic correction is applied, resulting in collisions. There is no problem in XeTeX or LuaTeX version 0.79.1. There is also no problem when using native TeX mathematics instead of `unicode-math`.

Since the `unicode-math` package has not been updated since before the start of the TeX Live 2015 pretest, I am guessing that the problem is in LuaTeX.
Steps To ReproduceSee attached testcase and output.

Actually, I think the problem is that italic correction is not being applied at all: if I delete the `italic` parameter in `texmf-var/luatex-cache/generic/fonts/otf/*.lua`, then the problem is reproducible in LuaTeX 0.79.1 as well.
