One more thing: I found that this is occurring because the test on line 83 of xetexdir/XeTeXOTMath.cpp is failing on 64-bit machines. This line is the line if (fontarea[f] == OTGR_FONT_FLAG) { in getotmathconstant(). On 64-bit machines, fontarea[f] == 0, instead of OTGR_FONT_FLAG(=65534). --Paul Vojta, vo...@math.berkeley.edu -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
