no, Gem uses pd's gpointer for it's data (which per se is a problem, but 
it is unrelated to the name clash)


i have finally made this test:
use pd from CVS and applied _only_ the string-patch (patch-#1646604)
(ok, this is not entirely true, i have also applied 2 very minor patches 
(#1826144 and #1822943) which do not have _anything_ to do with strings 
(e.g. the symbol "string" does not appear anywhere...)

i compile this version of Pd and load my Gem et voila:
class_addmethod: 0xb7c06540
consistency check failed: class_addmethod: textoutline_string: bad 
argument types
...

i consider this as prove that the problem is related to both Gem and 
your string-patch (and nothing else)

apart from that, Pd behaves weird now:
if i create a messagebox [string hallo( and click on it (with nothing 
connected) i get an error "error: messresponder: no method for string so 
far..."
