Bug#784874: mdadm --re-add Segmentation Fault

Package: mdadm
Version: 3.3.2-5
Severity: normal

I was trying to re-add some disks to a RAID, and mdadm crashed with a segmentation fault.
So i rebuilt mdadm with DEB_BUILD_OPTIONS=nostrip and backtraced the core dump in gdb, which yielded the following output:

# gdb mdadm core
GNU gdb (Debian 7.9-1) 7.9
 ...
For help, type "help".
Type "apropos word" to search for commands related to "word"...
Reading symbols from mdadm...done.
[New LWP 28013]
Core was generated by `mdadm --manage /dev/md/storage --re-add /dev/sdg /dev/sdh /dev/sdi /dev/sdj'.
Program terminated with signal SIGSEGV, Segmentation fault.
