FOLLOWUP: 1.5.12: problems without registry keys

[Andrew Que <que_andrew at yahoo dot com>]

   I apologise ahead of time, I could not for the life
of me figure out how to send a reply to a thread.  The
original thread is 101373: "1.5.12: problems without
registry keys"
  In my original post, I noted not all apps crashed
without the registry key.  So, I tried to narrow it
down.  It looks like apps. that use semaphores lock up
every time.

I attached an example of an app that will lock up
without the registry keys present.

To compile:
  gcc Semaphore.cpp -o Semaphore.exe

(PS. The example is just a semaphore coalition test--
and it's terrible code)
