Can't reproduce this on Linux. What is the full error message you get?
 [2004-03-07 16:16 UTC] su1d at phpclub dot net 
Just a common Windows system MessageBox appears notifying me about an error:

php.exe - Application Error
The instruction at "0x100007164" referenced memory at "0xfffffff8". The memory could not be "read".
Click "OK" to terminate the program
blah-blah-blah...

I'm sorry, but I have to admit that the bug remains in the newest build.

We need someone else to check the issue out on a Windows system.

I can confirm this bug with latest snapshot (php5-win32-200403261130).
I've no ideas how to debug it under win32, so if you tell me how to get the backtrace or something more useful, than this silly error message, I'll try to help, of course.

Please try using this CVS snapshot:

  http://snaps.php.net/php5-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5-win32-latest.zip

And note that the Reflection_Function is now renamed to ReflectionFunction..

Negative. 
The bug persists:

C:\>php -v
PHP 5.0.0RC2-dev (cli) (built: Apr  8 2004 16:16:41)
Copyright (c) 1997-2004 The PHP Group

C:\>php -r "$r = new ReflectionFunction('abs');"

C:\>php -r "$r = new ReflectionFunction('nofunc');"
** CRASH **
