Summary: run form fails in restored image
Initial Comment:
I have a test program which runs an external
program using a (run ...) form with redirection.
When I run from a saved image I get the following
run-time errors [and an image crash]:
drush@dubcvs: test foo bar
heap size 4000000 is too small, using 4361408
undefined imported name sch_tcflow
undefined imported name sch_isatty

wrong-number-of-arguments

scsh-level-0)}

Error: returning wrong number of values
(#{Procedure 11554 (unnamed in really-wait in scsh-level-0)} 10 -1 0)
Obviously the undefined imported names are not
interesting, but the wrong-number of arguments
and returning wrong number of values *are*
problems.
I am using scsh-0.6 built from the head of the CVS
tree on November 5.

I'm now almost sure that your scsh/syscalls1.c is not
up-to-date. In revision 1.22 wait_pid returned a list of
three elements, now in 1.23 there are only two elements.
This list is turned into multiple values in the Scheme code.

I followed the instructions in CVS_README:
set BUILD_RUNNABLE to local Scheme48-0.53
autogen.sh
configure
make
The error does *not* occur in interactive mode. That is why
I
submitted a bug report. I will try a rebuild and capture the
output for closer examination...

Did you redo the whole build process, including a cvs
update? Apart form that I'm a little bit helpless here. I
checked the source but could not find a place that would
match your error messages. I also tried your script on
Solaris 5.7, gcc 2.96 but did not have any problem.
Can you reproduce your error in the interactive mode and
gather some debugging information using ,debug?

Then how can I further diagnose/fix the problem? There are
no
messages originating from the program run in the subprocess;
whether or not Solaris underneath it all is complaining, I
have
no good way of diagnosing.
Could I be looking at some problems in my initial image?

Sorry, but for me the script is running fine:
aubisque[63] ./test foo bar
Long distance runner: foo bar
aubisque[64] less bar
this is a fake...
sablotron args:
/space/experiment/aolserver-3.4/servers/scrawler/scrawl/spider.xsl
foo
I think something with your build is wrong. The undefined
imported names also point into this direction. Another
problem is that the error messages look rather strange, they
seem to be out of sync. Is it possible that they originate
from the forked process?

I have a tarball of the files which I have been attempting
to
attach to this bug w/out much success. I've just changed
browsers in the hope that's the problem, but I can email
it whenever necessary...
If it has uploaded you need to untar and run tb.script. then
run the program test as above...
