skype-4.0.0.7-r2 segmentation fault

[ Edited ]

Hello,

 

I'm just updated my Gentoo-based Linux Skype to skype-4.0.0.7-r2 from sources.

The skype does not start after few start up. I've get the "segmentation fault" if I run it from terminal. And get tail in log file like this:

kernel: skype[4569]: segfault at 3f ip 0807dc0d sp bfd4c720 error 6 in skype[8048000+19ba000]

Then I just reinstall it and work fine till few starts. Then it's going to repeat.

Is there any idea to fix it? Or should I just use for old one version, which works so-so?

Very srtange behaviour of skype executable. It's modifying itself during run. So, there is decision (http://forum.xakep.ru/m_2657618/tm.htm):

 

chmod -w /opt/bin/skype

or

chmod -w /usr/bin/skype

depending of your distribution.

Re: skype-4.0.0.7-r2 segmentation fault

It's again:

 

Jun 25 22:23:34 calculate kernel: skype[15834]: segfault at 3f ip 000000000807dc0d sp 00000000ff877370 error 6 in skype[8048000+19ba000]

 

Now reinstalling.

Very srtange behaviour of skype executable. It's modifying itself during run. So, there is decision (http://forum.xakep.ru/m_2657618/tm.htm):

 

chmod -w /opt/bin/skype

or

chmod -w /usr/bin/skype

depending of your distribution.
