Bug 350321 – app-portage/eix-0.22.5 --end segfaults

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description John 2011-01-01 21:25:06 UTC]

Running eix with --end something results in seg fault:


Program received signal SIGSEGV, Segmentation fault.

I'm leaving the debug session open for some time.

have you tried with -O2 ?

Now I did, but didn't change anything.

[Comment 4 Mike Gilbert 2011-01-02 08:26:19 UTC]

Please update the summary with the version of eix you are using.

[Comment 5 John 2011-01-02 08:45:21 UTC]

Oops, sorry.

[Comment 6 Martin Väth 2011-01-02 20:50:48 UTC]

Thanks for the report:
There was an initialization command (USE_TEST) missing for O_END_ALGO in cli.cc
This is now fixed in eix svn trunk which will probably be >=eix-0.22.7

[Comment 7 Martin Väth 2011-01-02 20:56:05 UTC]

Until >=eix-0.22.7 is released you can use as a workaround the sequence
  --begin --end
instead of
  --end
(Reason: --begin does the required initialization of the PackageTest class)
