Whe I execute the script below direct from the command line (e.g.c:\>php crash.php), php crashes.
1.) the command "echo `perl -h`;" is executed, it displays the 'help desk' from perl correctly
2.) the command "echo `c:\\command.com /C echo hallo`;" is executed this runs and display "hello", but
3.) the command "echo `echo hallo`;" displays "...Warning unable to execute..." but shows the windows Application crash Dialog, after closing this Dialog the script terminate, without execute more lines.

Best regards
Ekkehard Domning
