http://sourceware.org/bugzilla/show_bug.cgi?id=15140 Nick Clifton changed: What|Removed |Added Status|NEW |RESOLVED CC||nickc at redhat dot com Resolution||FIXED --- Comment #6 from Nick Clifton 2013-02-15 14:38:22 UTC --- Hi Dmitry, The problem here is not the flattening of thin archives, but rather the fact that you are trying to convert a normal, non-thin, archive into a thin one. This is not supported, but ar should have produced an error message when the attempt was made. I have checked in a patch which fixes ar so that it will produce an error message. It also updates the documentation to make it clear that archives cannot be converted between normal and thin types. Finally the patch fixes readelf so that it no longer segfaults on the corrupted archive and nm so that it no longer goes into an infinite loop trying to read its symbol table.

1. It sets prev_filepos on success. The next call on the same

2. It checks prev_filepos without checking if archive is the same.
It caused PR 15151.
