Description Kevin Street 2010-11-13 16:37:51 UTC

Description of problem:
When creating an archive using the --listed-incremental option to tar, tar will segfault (return code 139). This only happens when archiving the root partition (/) and only on the second and subsequent invocations. (The first invocation creates the list file, the second should read the list file and archive only the delta changes).


Version-Release number of selected component (if applicable):
tar-1.23-6.fc14.x86_64

How reproducible:
always

Steps to Reproduce:
1. tar --create --one-file-system --listed-incremental=root.list --file=root.full.tar /
2. tar --create --one-file-system --listed-incremental=root.list --file=root.delta.tar /
3. echo $?
  
Actual results:
segfault errcode 139

Expected results:
delta archive into root.delta.tar

Additional info:

There is a patch for this floating around upstream.  See:

My test case is a little bit different and segfault on last fedora 14.
It is working fine on F11 and centos5.

I tried tar-1.26 and it works too, no segfault.
