If you shrink down CFLAGS to "-O -pipe", does it make difference? Someone told me that he had similar problem but when he built emacs with USE="debug" (with the same CFLAGS) he didn't have the problem.
neither changing cflags nor using "use=debug" can solve this issue.
After emerge -u world, emacs works again.
might be caused by borked libraries... thanks for your cooperation.
after rebooting my machine, I got that phenomenon again. Here is the result I use strace to fllow emacs: ... gettimeofday({1096859982, 424789}, NULL) = 0 --- SIGIO (I/O possible) @ 0 (0) --- sigreturn() = ?

Could you use sys-apps/memtest86 or something to test whether your memory is corrupted?
It should not. I have this problem on two machines. One is Pentinum III, another is AMD XP. At least the memory on AMD XP machine is good.
It seems it is a problem of xorg. After I reemerged xorg-x11, the problem is solved
What happens if you run Emacs with -nw, thus preventing it from loading the X interface?
I assume the problem was solved (by remerging xorg-x11). Thanks for your cooperation.
