I have a rather frustrating problem with php/freetds

freetds: 0.63
php: 4.4.0
apache: 2.0.54
Web Platform: Solaris 9
DB Platform: SQL 2000 on Windows NT OS

Symptom:

performing a query such as 

SELECT AVG(cast(wr.gstage as float)) as gstage from WeekReport wr

kills the script stone dead (resulting in a "the page cannot be displayed" 
browser 
message).

Whereas SELECT AVG(wr.cplant) as cplant from WeekReport wr

works fine (I DO need to do the cast).

The log looks like this:

Any help would be gratefully received as this is driving me mad..

Thanks in advance
