Markus,

Why are you calling bash with the -i option in this context?  Your first 
`nil' causes bash's input to come from /dev/null.  Does it make sense to 
have an interactive shell with input coming from /dev/null?  If you 
remove -i and just run

(call-process "bash" nil '(t t) nil "-c" "ls -al") ,

it works fine with both cygwin 1.7.9 and the latest snapshot.

Maybe there's still a Cygwin bug here; I tested your original command in 
Linux, and it worked.  But omitting -i might at least be a workaround 
for you.

Ken
