Without any specifics about the crashes or the code used by glib 2.x, I 
couldn't say.  We were running a tinderbox using WS6U2 + system updates 
for about 3 months and the runtime tests worked fine.  The Sun engineers 
claim that -xO5 with 6U1 is what they use on their build machines so if 
there were any problems, I would have expected them to be caught by now.
