The following patch avoids the dereferencing of
a null pointer, which led to an ICE. The patch
here is a slight variation on the patch submitted
by drikosev at otenet dot gr. The testcase is a
slight variation on the code submitted by FX.
Built and regression tested on x86_64-*-freebsd.
OK to commit?
