- The following perl script will create a 250 character file that will crash
- WinNT (service pack 3) explorer when right-clicked on:
- --------------------
- $fn = 'A' x 250;
- open (FH,">$fn") or die ":$!\n";
- print FH "it worked?";
- close FH;
- --------------------
-
- You may have to create the file inside a subdirectory. I think what is
- happening here is the path+filename exceeds MAX_PATH.
-
- To delete the file drop to a command window and delete it using it's
- shortname (dir /X will display shortnames).

- (note the chr(160)'s at the end) It is 235 characters in length. After
- creating it on my desktop, I right clicked on it; explorer crashed saying
- it caused an illegal operation. the only way I found to close this was by
- using command.com I sent this to a friend and he got the same error.

- I tried the same under Windows NT 4 Workstation SP3, except the file name
- length was only 225 bytes, called "hello.txt(lots of spaces)(chr(160))", and
- Explorer crashed as well here.
-
- It seems to be an Explorer-only bug, as no other application I've tried went
- down.
-
- Oh well, another buffer overflow..
