Works for me, after two minor changes (my version attached):

- I used the original bash URL, not your local path (it should work
for you now you've downloaded bash with the OCaml version).

- I used a different interface (0compile) for the dependency, since
you used a local path.

I got:

Executing: [u'/bin/bash', u'-c', u'"$@"', u'-', u'c++',
u'/tmp/test.cpp', u'-o', u'/tmp/0compile-iA0bJX/test-any-any/test',
u'-I /home/tal/Projects/zero-install/0compile/include']

(note: you should remove the space after "-I" or split it into two arguments)
