Comment 2 Huang Hang 2013-05-10 00:11:12 UTC
When I tried to remove the suspicious plugins causing the segmentation fault, 


#14 psz_file=0x6d9ab0 "../modules/codec/.libs/",

Then ./vlc-cache-gen ../modules can run until exit normally.
Comment 3 Huang Hang 2013-05-10 00:19:47 UTC
I also rm /usr/lib64/vlc/plugins/codec/ to make VLC free of runtime segmentation (also happened in module_Load(), same as vlc-cache-gen). Then I lost the subtitle display in VLC....

So I'm suspecting that some plugins are broken with recent version of VLC.

There's an old bug which might related to this issue.
Unfortunately it didn't catch enough attentions and not get resolved yet.

VLC 2.0.6 emerge failure build.log

Why put a single file in a tar archive?

Comment 7 Huang Hang 2013-05-11 15:50:10 UTC
Because the original build.log is larger than 1000KB....

So I have to compress it. But I realized that you're suggesting using gzip instead of 'tar czf'. I think you need to uncompress anyway, so it won't cause more trouble with .tar.gz than .gz .

Comment 8 Huang Hang 2013-05-11 15:59:40 UTC

Do we have enough resource to track this bug down nowadays? Maybe we will have other findings if this is not reproducible for everyone (e.g., some conflicts with other package which is not quite widely installed).
