Subject: B20.1: ls.exe hangs when repeatedly invoked in perl script (from
bash.exe) 

on NT 4.0 SP4
I use b.bat to start BASH
then enter:
which2 which2  
which2 which2 
which2 which2 (about three time) 
and it doesn't return after the last one.

The reason for invoking so often was I was trying to test the perl script that would perform a which that would list all occurances of the command in all the $PATH.
It works the way it was intended but I just can ues it more than twice.

After it hangs the task Task Manager shows that ls.exe is running and accumulating more and more memory. (i.e. the "Memory usage" is increasing) so it appears that ls.exe is stuck in some loop.

No need to repond just reporting problem.

My fix is to close the BASH window and start another session.



b.bat
====
@title "GNU bash, version 2.02.1(2)-release (i586-pc-cygwin32)"
@call c:\tools\cygnus\cygwin-b20\cygnus.bat
@exit


which2 (perl script)
===============
#!perl
sub ls 
{
   my @output = `$_[0] 2>nul`;
   if ( $#output > -1 ) {
      print @output;
   }
}

    foreach $file (@ARGV) {
        foreach $dir (split(/;/,$ENV{PATH})) {
           &ls( "ls -l '$dir'/$file" );
           &ls( "ls -l '$dir'/$file.*" );
	   my $cmd = $file;
	   $cmd =~ tr/a-z/A-Z/;
           &ls( "ls -l '$dir'/$cmd.*" );
        } 
    }
