Rackspace driveclient on RHEL/CentOS segfault

The issue in
http://www.transdimensia.ravenhurst.com/2012/12/libstdc-dies-running-driveclient.html
is alive and well, although with a slightly different signature:

This is the line from /var/log/messages:


Oct  9 16:29:09 <hostname> kernel: driveclient[28672] general protection ip:7f06ec55e867 sp:7fff0a73adb0 error:0 in libgcc_s-4.4.7-20120601.so.1[7f06ec54f000+16000]

You might receive the following in strace:

stat("/etc/issue", {st_mode=S_IFREG|0644, st_size=1882, ...}) = 0 stat("/etc/issue", {st_mode=S_IFREG|0644, st_size=1882, ...}) = 0 open("/etc/issue", O_RDONLY) = 3 read(3, " _ ____ ___"..., 8191) = 1882 --- SIGSEGV (Segmentation fault) @ 0 (0) ---

Dancer's Shell (DSH) CentOS6 rpm

Haven't really done much rpm packaging before, so I tried it out on a package I haven't found elsewhere yet. DSH is a package that allows you to distribute commands out among different hosts in parallel.

These are CentOS6 x86_64 binaries for dsh and libdshconfig.

libdshconfig -

dsh - 8e5f989a6f539475ff882b493750c14d
