Hi, something in the past days has killed my gcc for root. Normal users can run gcc without problems but for root it stops in an infinite loop (look at strace output below). Rerunning gcc-config doesn't solve anything and it only happens when gcc is called directly by root, e.g. it works in emerge. emerge info and the strace output for gcc as root and non-root are below Bye gcc as root (strace output): asgard slomo # strace gcc execve("/usr/bin/gcc", ["gcc"], [/* 51 vars */]) = 0 uname({sys="Linux", node="asgard", ...}) = 0 brk(0) = 0x804b000

re-emerge gcc-config run `gcc-config` for the proper toolchain unset GCC_SPECS in your env source /etc/profile everything should work
works... thanks :)
k, i'll talk to lv about getting a proper fix
