bug: beta 20.1 under NT 4.0 with SP4 and IIS4 - 1 of 2



Greetings.

When using httptunnel with your cygwin under NT 4.0 with SP4 and IIS4 I get a GPF.

httptunnel is from:
http://www.nocrew.org/software/httptunnel.html

and I got your latest software from:
ftp://go.cygnus.com/pub/sourceware.cygnus.com/cygwin/latest/

----

Here is how I caused the GPF:

On the same machine I typed:

hts -F nyx.net:23 8899
htc -F 2323 -P proxy1.emirates.net.ae:8080 my.ip.address:8899

...where "my.ip.address" = the IP address I currently have as from my ISP.

Next I brought up the telnet supplied with NT and telneted to localhost:2323. Then Dr. Watson came up and gave an error.

Here is the log from Dr. Watson:
