This error still occurs with xine-lib-1_rc2. A related error also occurs with media-video/avidemux that is fixed by increasing the -O level to -O1 or higher. I'll get that error message shortly.

added this to 1_rc4-r1: is-flag -O? || append-flags -O1
*** Bug 55553 has been marked as a duplicate of this bug. ***
This: ( is-flag -O? || append-flags -O1 #31243 ) in xine-lib-1_rc5-r2.ebuildxine-lib-1_rc5-r2.ebuild ALWAYS adds -O1 to the flags, and BORKS amd64 on GCC 3.4 I suspect you may have wanted: is-flag -O0 || append-flags -O1 or some such..
