Indeed, I was right. Problem is gone after hashing out CPUTYPE line, building world with GCC, and with clang after that. Now world is building without problems. But hey, i just realized that: # dmesg | grep -i cpu CPU: mobile AMD Athlon(tm) XP 2200+ (1800.11-MHz 686-class CPU) I simply forgot that about a year ago I changed Athlon XP in this BOX to Athlon MP and I didn't changed CPUTYPE in make.conf... So maybe clang in fact did exactly what it should and created binary designed to other CPUTYPE ;) I don't know exact differences between Athlon XP/MP architecture (registers specially) but I just started another try with CPUTYPE=Athlon-mp and I will post results :) -- Bartosz Stec -- IT4Pro Bartosz Stec http://www.it4pro.pl tel: 607041002 E-Mail: bartosz.stec@it4pro.pl
