Bug 114628 – eix-0.5.1-r2 stabilization WAS: app-portage/eix 0.3.0-r2 gets SIGSEGV if it's compiled with gcc 3.4.4 and -O2

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Daniel Plaza 2005-12-06 08:23:51 UTC]

I have updated gcc to 3.4.4-r1 in my alpha and I have compiled app-portage/eix
0.3.0-r2. When I run "update-eix" I get:

# update-eix 
Reading Portage settings ..
Received SIGSEGV - you probably found a bug in eix.
Please post the output of eix -V along with your bugreport.
Sorry for the inconvenience.

The output of eix -V is:

# eix -V
eix 0.3.0 (gcc-3.4.4, alpha-unknown-linux-gnu)

If I compile eix without -O2 it works. Also If I compile eix with debug (and
-O2), "update-eix" and "eix" work fine so I can't debug them.

[Comment 1 Emil Beinroth 2005-12-08 11:26:27 UTC]

Does app-portage/eix-0.5.0 work?

[Comment 2 Daniel Plaza 2005-12-09 03:46:39 UTC]

  app-portage/eix-0.5.0 doesn't work if it's compiled with -O2. If I remove -O2
it  works fine.

[Comment 3 Daniel Plaza 2006-02-08 09:38:54 UTC]

  Same problem with eix-0.5.1-r1.

[Comment 4 Emil Beinroth 2006-02-09 09:46:20 UTC]

Created attachment 79340 [details, diff]
Workaround for the bug.

I've tested eix on a alpha-box of a friend, and I can't find anything wrong with the code.
But this patch somehow removes the segfault.

[Comment 5 Daniel Plaza 2006-02-09 11:56:39 UTC]

(In reply to comment #4)

Thanks, with that patch it works ok, but I can understand why. 

[Comment 6 Daniel Plaza 2006-02-09 11:56:39 UTC]

(In reply to comment #4)

Thanks, with that patch it works ok, but I can understand why. ¿Only moving a variable declaration can make it work? ¿Maybe GCC problem?

[Comment 7 georg.lippold 2006-02-20 14:23:09 UTC]

the patch doesn't work for me on 0.3.0.

[Comment 8 georg.lippold 2006-02-23 07:54:20 UTC]

I played a bit with gcc options and found out that eix doesn't segfault if compiled only with CFLAGS=CXXFLAGS="-O2 -pipe". If I compile it with "-march=pentium-m" however, it segfaults regularly. Maybe really a bug in gcc-3.4.4?

[Comment 9 georg.lippold 2006-02-23 07:59:35 UTC]

I was wrong, it is "-fomit-frame-pointer" that causes the issue.

[Comment 10 georg.lippold 2006-02-23 08:09:03 UTC]

Sorry for spamming you. I was wrong again. It works if compiled with "-O2" but without it, it segfaults.

> the patch doesn't work for me on 0.3.0. 

Please try the ~x86 version of eix.
PS: This bug is for alpha, you have x86.

[Comment 12 Jeroen Roovers (RETIRED) 2006-03-15 15:55:14 UTC]

No bugs for 0.5.1-r2 outstanding and it WORKSFORME... Might I suggest we move for stabilizing a 0.5.1 ebuild?

[Comment 13 Stefan Schweizer (RETIRED) 2006-03-15 16:22:18 UTC]

yes, jer please mark stable if you have a stable system.

[Comment 14 Stefan Schweizer (RETIRED) 2006-03-21 13:07:36 UTC]

x86 team: please stabilize 0.5.1-r2

[Comment 15 Stefan Schweizer (RETIRED) 2006-03-21 13:36:49 UTC]

arches please test app-portage/eix-0.5.1-r2 and mark stable

[Comment 16 Matthias Langer 2006-03-22 03:55:28 UTC]

I've just installed eix-0.5.1-r2 for testing against x86. I've done eix-sync and about 15 searches with different options (-S -C -r ...), and everthing seems to work as expected.

You seem to have forgotten to actually CC the arches.

And now I was having the same problem. 8-)

[Comment 19 Jeroen Roovers (RETIRED) 2006-03-22 14:49:44 UTC]

Forgot to add ppc-macos.

Stable on hppa!

[Comment 20 Andrej Kacian (RETIRED) 2006-03-22 16:18:26 UTC]

I've been using 0.5.1-r2 since it was added to portage, and it looks good. Stable on x86.

[Comment 21 Luis Medinas (RETIRED) 2006-03-22 16:43:02 UTC]

stable on amd64.

[Comment 22 Joe Jezak (RETIRED) 2006-03-24 22:47:55 UTC]

Hansmi has already marked this ppc stable.

sparc stable.

[Comment 25 Thomas Cort (RETIRED) 2006-04-01 05:29:53 UTC]

I tested app-portage/eix-0.5.1-r2 on alpha. It compiles and works. Alpha team, please add the alpha keyword.
