Frederic, have you looked at this one yet?

> Frederic, have you looked at this one yet?

Sorry, I didn't have time to look at that. I'm just doing a quick verification now and that seems to be something related to the "logical heights" that are not handle correctly (probably I should specify the mspace height). But these  "logical heights" have caused problems in the past and I think Martin Robinson has a patch to remove the code that raise this assertion. I'll cc' you to the bug.

bug 118601, comment 6 fixes the asserts.

So it seems the test for lengths is now failing on Mac. It didn't before the change to LayoutUnit (which is essentially using int instead of float). I'm trying to modify the computation to mimic what CSSPrimitiveValue does. Probably, the MathML parsing functions should be moved to CSSPrimitiveValue.cpp later so that they can call conversionToCanonicalUnitsScaleFactor.
