 Do you still see this problem with 0.30 ? If yes, which programs 
 produce a gc.log file ? Is it all programs, or just programs which
 crashed etc ?

+It happens with almost every program run with mono, from simple
+console program to xsp. And it happens with mono-0.30 under windows.
+
+I wouldn't mind that much if it were put under %tmp%, --now it is
+created always in the "current work directory" or aspnet root
+directory. I'm not sure whether it will adversely affect the programs
+when the current work directory could be readonly.
+
+Search found "gc.log" in mono\libgc\misc.c, maybe it's there.
