Description emerald 2007-07-22 16:59:56 UTC

i try to update gcc for powerpc-unknown-linux-gnu from 4.1.2 to 4.2.0 but it fails with a segmentation fault from ld
gcc-4.1.x was installed using crossdev, updates since run automatically via emerge -auND world

i tried almost everything possible:
MAKEOPTS="-j1",
CFLAGS="-march=athlon64 -O2 -pipe",
without ccache
re-emerge-ing binutils with minimal CFLAGS
nothing helps, it always crashes
first with fortran use flag activated it crashed somewhere in fortran or fortran lib, without fortran it crashes in libstdc++-v3

i have crosscompiler for i686-pc-linux-gnu and sparc-unknown-linux-gnu, both compile/update fine

does it fail at exactly the same spot everytime ?

Comment 5 emerald 2007-07-22 20:15:58 UTC

yes, always fails at the same spot, linking libstdc++-v3
(withfortran i don't know now, but also always happened at the same spot there)
if it weren't always failing at the same spot i'd check my system for hardware errors but since it is always the same spot whereas _everything_ else compiles fine, even gcc-4.2.0 for sparc and i686 (and sure, for amd64 too), i filed this bug. i tried to recompile glibc (sometimes strange things seem to happen there) recompiled gcc-4.2.0, gcc-4.1.2 (amd64), no success
i also checked for unusual temperatures and everything, nothing

Comment 6 SpanKY gentoo-dev

upgrade your cross binutils and it should work fine

i'm not really inclined to investigate/fix this for 2.17 if a newer version already addresses the problem

Comment 7 emerald 2007-07-23 03:19:45 UTC

since there's no newer binutils for ~ppc/+ppc i used the +ppc64 binutils and gcc merges successfully
(if newer binutils work well on ppc, maybe those could be marked ~ppc so it's automatically upgraded without manual interaction when upgrading the system)

thanks alot

that's really up to the ppc team

This should be fixed now that binutils-2.18 is in the tree and marked ~ppc.  Please re-open if you're still having problems.
