my current CFLAGS are CFLAGS="-march=athlon-tbird -mcpu=athlon-tbird -Os -pipe -fomit-frame-pointer -ffast-math" when i add "-frename-registers", all programs work just fine. HOWEVER, when i tried to use mozilla-thunderbird, the program would build fine, and start fine. But after about 3-4 seconds, the program would quit out. No errors to the command line. I realize that this is an issue with CFLAGS, and i don't expect this bug to get fixed, but i'm just letting you guys know. If you can fix it... great... if not... oh well. Reproducible: Always Steps to Reproduce: 1.add -frename-registers to /etc/make.conf 2. emerge mozilla-thunderbird 3. start thunderbird... and watch Actual Results: the program quit( no errors) unexpectedly Expected Results: continued running until i tell it to quit Portage 2.0.49-r15 (default-x86-1.4, gcc-3.3.2, glibc-2.3.2-r8, 2.4.21-pfeifer-r 1_pre4) ================================================================= System uname: 2.4.21-pfeifer-r1_pre4 i686 AMD Athlon(tm) Processor Gentoo Base System version 1.4.3.11 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CFLAGS="-march=athlon-tbird -mcpu=athlon-tbird -Os -pipe -fomit-frame-pointer -f fast-math" CHOST="i686-pc-linux-gnu" COMPILER="gcc3" CONFIG_PROTECT="/etc /var/qmail/control /usr/kde/2/share/config /usr/kde/3/share /config /usr/X11R6/lib/X11/xkb /usr/kde/3.1/share/config /usr/share/texmf/tex/ge neric/config/ /usr/share/texmf/tex/platex/config/ /usr/share/config" CONFIG_PROTECT_MASK="/etc/gconf /etc/env.d" CXXFLAGS="-march=athlon-tbird -mcpu=athlon-tbird -Os -pipe -fomit-frame-pointer -ffast-math" DISTDIR="/usr/portage/distfiles" FEATURES="sandbox ccache autoaddcvs" GENTOO_MIRRORS=" http://gentoo.oregonstate.edu http://www.ibiblio.org/p ub/Linux/distributions/gentoo http://gentoo.noved.org " MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 oss apm avi crypt cups encode foomaticdb gif jpeg gnome libg++ mad mikm od mpeg ncurses nls pdflib png quicktime spell truetype xml2 xmms xv zlib gtkhtm l gdbm berkdb slang readline arts tetex bonobo svga java X sdl gpm tcpd pam libw ww ssl perl python esd imlib oggvorbis gtk qt kde motif opengl cdr"
EDIT ebuild with: filter-flags -frename-registers perhaps?
Since this hasn't cropped up again, I'll close it for now, esp since newer versions of Thunderbird are now available.
