Bugzilla Bug 114628

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.

Does app-portage/eix-0.5.0 work?

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

  Same problem with eix-0.5.1-r1.

Created an attachment (id=79340) [edit]
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.

(In reply to comment #4)

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

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

the patch doesn't work for me on 0.3.0.

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?

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

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.

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

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

x86 team: please stabilize 0.5.1-r2

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

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-)

Forgot to add ppc-macos.

Stable on hppa!

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

stable on amd64.

Hansmi has already marked this ppc stable.

ppc-macos stable

sparc stable.

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