Looks like a 0-pointer dereference. Accordingo to /proc/<pid>/maps, the
location of the faulting instruction is part of wget's code segment
(i.e. it's not a shared library that causes the crash):

Hello,
the problem is reproducible in 1.13.4-3 in wheezy on different archs and
it is fixed in 1.14-4 in testing/jessie and sid.
I don't think it is possible to get the new upstream release 1.14 into
wheezy.:( So it will be fixed for the stable users with the next stable
release (afaik 2014).
Regards.
