Indeed it was; the problem happened for at least two other people on the
mailing list (including me) and a fix was implemented in the developer
snapshot of cygwin1.dll and fixed it for us.

Since you are using non-Cygwin programs, you should also be setting the
pipe_byte option of the CYGWIN environment variable.  Search the mailing
list archive for why this is so, but to summarize - there are situations
where the non-Cygwin programs may malfunction when processing their standard
input streams if this option is not set.  (Unfortunately, there is not yet
any documentation about this recent issue.)
