1.11.8 AND -M -F

[Anne M. Hammond]

When using -M (multivolume) and -F (script to execute between
tapes), when gnutar reaches end of tape (EOT), it outputs the message:

/usr/local/bin/gnutar: (null): Bad address
/usr/local/bin/gnutar: (null): Bad address

But the tape is never changed, and gnutar sits, outputing the
above message multiple times.

This is the script:  

/usr/local/sbin/mtx next 2 0 >> /tmp/mtx.out 2>&1
echo "changing tape" | Mail -s "InfoScript" hammond 

The script is mode 755.

When gnutar waits for the script the script to be executed,
mtx reports failure to change the tape.  

The tape cannot be accessed via software (resource busy) or via
the library front panel. Error messages from the script indicate
changing the tape failed.  So it sounds like tar holds the device.

We are using the rewind device (tps5d2nsvc).

If you background the tar, the tape can be unloaded via mtx and 
the next tape can be loaded.  But then tar quits :)  

The results above are from gnutar 1.11.8.  I am now trying 1.3.

Is there some unique "form" to the InfoScript?  The gnu documentation
doesn't indicate so.

This is running on an SGI under the most recent version of IRIX
6.5.16.  

If there is some way to troubleshoot this and determine if this is
an IRIX issue, I'd really appreciate it.   

Thanks in advance,
