Subject: Bash page fault / b20.1
Content-Type: text/plain; charset=us-ascii

Dear All,

====
Please first note that I am not subscribed to the mailing list and
I usually use
  Alain.Culos -at- bigfoot.com
rather than the above address.

Intro :
I've been using bash/cygnus tools for a while now (since b17) and I am
now using b20 + mingw32 egcs 2.95.
I love all these tools they are pretty darn good.

Now to the point :
I managed to get a page fault in bash with the following :

create a small shell script containing :
1: #!/bin/sh
2: tar -cf archives.tar.bz2 --use-compress-program=bzip2 \
3:./arc    \
4:~/dir-for-archive
5:tar -tf archives.tar.bz2 --use-compress-program=bzip2 >
.archives.txt
6:gvim .archives.txt &

When you run it, it always shows an M$-WZ pop up window with a page
fault re. SH ; it also randomly shows a broken pipe in the shell
window as if bzip2 was expecting something ... when one puts "echo's"
in the script file one can see the second bzip2 is the one targeted by
the error message.
Note that gvim is a windows GUI app.

The funny thing is that when you change the last line of the shell
script to :
6:gvim .archives.txt
i.e. just take out the final '&'
then all is fine in the best of the worlds.

Other than that execution seems to be normal despite the error
message[s].
However it is always irritating to see a page fault and you wonder
whether the job completed properly.
