problem with redir test

[Vladimir Marek]

Hi,

during testing of latest bash on Solaris I found strange behavior. We
run the tests with clear environment (env -). It seems to be caused by
undefined SHELL variable. The test reported

150,151c150,151
< ./redir11.sub: line 26: echo: write error: Bad file number
< ./redir11.sub: line 27: echo: write error: Bad file number
---
> ./redir11.sub: line 26: $(a=4 foo): Bad file number
> ./redir11.sub: line 27: $(a=4 foo): Bad file number


As a workaround I am using the attached patch although I don't feel that
it looks like a proper fix. Maybe it's a thing worth investigating? Can
you reproduce the issue?

Thank you
