Hi, If one does libm compile with -march=pentium4, there seem some math related functions be broken. -march=pentiumpro still works fine. Happens with gcc 3.1.1 and gcc 3.2.1 prerelease. Ports which are broken with libm and -march=pentium4 - xmms (no sound) - mpg123 (no sound) - openoffice (no text everywhere and no menues) So until this is fixed, people should stay away from using -march=pentium4. I'll see if I can find the broken function. -march=athlon seems to work fine. -march=pentiumpro seems to work fine -march=pentium seems to work fine So don't use CPUTYPE?=p4 in your /etc/make.conf. Looks like there could be some crashes related to this one. Bezier and X-Server crashes ? Or is nobody using CPUTYPE?=p4 ?
