Bugzilla Bug 78306

$ sudo gcc-config x86_64-pc-linux-gnu-3.4.3
* Switching to x86_64-pc-linux-gnu-3.4.3 compiler...
/usr/bin/gcc-config: line 1:  6156 Segmentation fault      cp -a "${ROOT}/${LDPATH}"/libgcc_s.so* "${ROOT}"/lib/

The number of bytes into the file changes each time (the number after line 1:), but the result is always the same.

Reproducible: Always
Steps to Reproduce:
1.
2.
3.

eradicator: gcc-config copies $LDPATH/libgcc_s.so to /lib/ ... this is probably
not right for multilib setups ;)

ideas ?

blech... ugly ugly... blech... ok... I'm looking at it.

We should use lib/$(gcc <multilib options> --print-multi-os-dir) as a proper fix... I'll put some extra info into the config file to handle this and bump gcc-config as well... if not tonight, it'll be after I get back from snowboarding.  I don't believe any 2005.0 profiles will be affected by this as amd64's 2005.0 still uses lib as a symlink to lib64, and ppc64 has always done the same.

Erick: please provide your 'emerge --info'

Here is my emerge --info (this is from a downgraded version of gcc (3.4.2-r2)
since 3.4.3 is broken, but nothing has changed except the gcc version to cause
this bug)

I am also having the same problem. Attached is the output, and the emerge info:

I should also mention that when I attempt to switch to gcc 3.3.4-r1 the same error occurs

i686? That would imply that it's not multilib-related, wouldn't it?

yes, it seems it's not restricted to multilib profiles...

I don't see why that would possibly segfault... vapier?

Created an attachment (id=49098) [edit]
strace -ff -eopen gcc-config

Here is an strace output of the offending command. I used 'strace -ff -eopen
gcc-config 2' as the command string.

If there are any other arguments I should add.. please let me know and I will
be happy to paste them.

gcc-config-1.3.9 fixed this for me, I think. After upgrading gcc-config,
waiting a while, then trying 3.4.3 again, it worked fine.

I am using gcc-config 1.3.9

I am going to downgrade to 1.3.8-r4, and see if I can test there, and then back to 1.3.9

Could it possibly be a toolchain issue?

Downgrading to 1.3.8-r4 got rid of the problem for me.

that doesn't make sense as that stuff isn't changed between 1.3.8 and 1.3.9. 
The major changes in those versions is the wrapper, not the config script... 
can you go back up to 1.3.9 just to verify?

can you please try 1.3.10

*** Bug 85509 has been marked as a duplicate of this bug. ***

emerge -v --oneshot '>=sys-devel/gcc-config-1.3.10' seg.faults for me as well.

emerging gcc-config-1.3.8-r4 gives me a Segmentation fault, as well...

Is this still an issue?  It works fine for me.
