After various different attempts to nail down this issue I have some hope
now that I have found a fix for it. I analyzed the changes of last to
current version of tcsh and found one that is related to context of the
problem and somewhat suspicious as well. The change I did then was the
following:
$ diff -uN sh.glob.c.orig sh.glob.c
--- sh.glob.c.orig 2012-09-17 13:20:26.212401000 +0200
+++ sh.glob.c 2012-09-17 13:20:23.916171400 +0200

/* The F_BACKQ flag must set so the job output is correct if
* printexitvalue is set. If it's not set, the job output

- t->t_dflg = F_BACKQ|F_NOFORK;
+ t->t_dflg |= (F_BACKQ); /*|F_NOFORK);*/
if (seterr)
stderror(ERR_OLD);
#ifdef SIGTSTP
The comment along with the change of t_dflg was added in latest tcsh
release.
Main change from me was to not set F_NOFORK. That fixed my test case.
Whether
or not it is ok to overwrite t_dflg or simply add the bit I can't say. I
tried both.
It made no difference for my test case.
I know that this is probably not the right forum to post this, since the
issues seems
to be in tcsh but not in cygwin. However, I thought I post it here for
the other
folks suffering from this problem as well. Maybe they want to try the
fix as well.
