Bug#809685: lvm2 on sparc64 = bus error

[Anatoly Pugachev]

Package: lvm2
Version: 2.02.138-1
Severity: important

Dear Maintainer,


   * What led up to the situation?

installed sid/unstable to sparc64 LDOM, any commands from lvm2 give "bus error":

root at deb2g:~# lvm vgs
Bus error
root at deb2g:~# lvm pvs
Bus error
root at deb2g:~# lvm lvs
Bus error

   * What exactly did you do (or not do) that was effective (or
     ineffective)?


I have to recompile lvm2 debian package with debug info, to provide a
more useful bug report:

$ export DEB_BUILD_OPTIONS="debug nostrip noopt"
$ fakeroot apt-get source -b lvm2
$ dpkg -i *.deb

set ulimit -c to unlimited and generated core dump:

root at deb2g:~# lvm lvs
Bus error (core dumped)

root at deb2g:~/lvm2-2.02.138/lib# gdb -c ~/core lvm
