Hi, we saw this during wineconf http://test.winehq.org/data/010119085b4cee3d7edbad2c5a46d35daa95000d/linux_m... the actual instruction is: cvttsd2si $xmm0, $eax which receives a FPE trap as the content of $xmm0 does not fit into $eax. http://www.jaist.ac.jp/iscenter-new/mpc/altix/altixdata/opt/intel/vtune/doc/... This means someone switched on FPE traps for XMM instructions in $CR4 register, which I would expect freetype2 the prime candidate if it is not Wine itself. Debugging shows that capEmHeight and capXHeight are both values < 0. long story short, in the loader we get these values: fixme:font:get_outline_text_metrics L"Goha-Tibeb Zemen" sCapHeight=-32768 fixme:font:get_outline_text_metrics L"Goha-Tibeb Zemen" sxHeight=-32768 The documentation does not give 0x8000 a specific meaning in the OS2 table. I can provide this font if needed for debugging. Ciao, Marcus
