Definately should be fixed.
thanks. I had to fix one small but important thing. Using commit message: ------------------------------------------------------------------------------ - fix improper use of hardened flag when pic flag should be used ------------------------------------------------------------------------------ /var/cvsroot/gentoo-x86/media-libs/flac/ChangeLog,v <-- ChangeLog new revision: 1.119; previous revision: 1.118 /var/cvsroot/gentoo-x86/media-libs/flac/flac-1.2.1.ebuild,v <-- flac-1.2.1.ebuild new revision: 1.2; previous revision: 1.1 ---- In reality because this textrel is in a lib.so this should be fixed properly as this version is introducing a regression system wide.
Created attachment 131458 [details, diff] textrel fix for flac how about this one?

Created attachment 132050 [details, diff] updated patch i forgot that the plt stubs also need ebx to be set up, let's try another approach.
