Works fine here.
What server API have you tried? CLI? Apache? Apache2? Other?
 [2004-08-22 19:57 UTC] iliaa@php.net 
What C library are you using, the error you are reporting 
implies that in "" or "*" conditions the library would 
return NULL as the path.

Please mark this bug as BOGUS... Looks like my system is 
totally screwed, glob() in my glibc is using some 
different structure glob_t than rest of the world...
 [2004-08-23 08:36 UTC] derick@php.net 
Ok, marking bogus then. What specific version glibc do you have?
 [2004-08-23 16:53 UTC] mg at iceni dot pl 
Some pre 2.3.3 version from CVS downloaded around a month 
before official release. So I guess that's the reason... 
strange because everything else is working flawlessly. 
Looks like it's time to reinstall this mess 8)
