Yes.  But without details on your bash version, it's hard to say if it 
is a known bug (that may have since been fixed in later bash).  In the 
devel branch of bash.git, I see examples/loadables/basename.c, but that 
does not seem to be built by default. It could very well be a bug in 
that file - but you should tell us for sure that you are using it.

bash 4.4 did not ship with a basename builtin.

That output corresponds to GNU coreutils, which is not testing the same 
program.
