Subject: "General Protection Fault " after third run of an external program

Hi!

I invoke an external command the following way:

...
execThis = "c:/WINNT/tar_dos.exe -cf " + $tarFileName + " " + $nameList
win_system(execThis)
...

I defined win_system the way I saw it on the list:

def win_system(command)
     Win32API.new("crtdll","system",['P'],'L').Call(command)
end

Now, when I start my program (on Win2000) it works fine.
Starting again is most of the time OK too.
But mostly on the third time I get this error (copied from irb shell):

Exiting due to signal SIGSEGV
General Protection Fault at eip=0001607f

Call frame traceback EIPs:
  0x0001607f
  0x00016005
  0x0001481a
  0x000148d1
=> 0

After such an error I have to close the DOS Shell where I was started the
program
with irb, and open a new one to get it work again.

Any idea why this happens?

Best regards,
Steve
