Created attachment 844793 [details, diff] Patch proposal to fix mplayer build with USE="libass" and CFLAGS="-flto" This patch is an improvement from the one previously submitted for the same bug for version 1.3.0-r4: https://bugs.gentoo.org/650458 The improvment is quite small: instead of globally disable HAVE_INLINE_ASM_DIRECT_SYMBOL_REFS, I disable it only in the faulty file in order to avoid potential side-effects in other build files and make sure we get proper optimizations, apart from this particular file, ie libmpcodecs/vf_ass.c. It seems that this patch could be applied conditionnaly to is-flagq '-flto' but it may be safer to always apply it. Following the build log from a successful merge with this patch applied (conditionnaly to LTO set in my case).

I think it's a bit too invasive to apply downstream. *** This bug has been marked as a duplicate of bug 650458 ***
