Does it make any difference for gcc.c-torture/compile/20001226-1.c? And of course it won't make any difference if you have enough memory that you never need to garbage collect without your patch. I would like to see us implement this general GC approach even if we don't wind up moving the basic blocks into it today. But we'll have to figure out what to do for PCH. I guess the general approach would be to provide an optional swizzling routine as well as the marking routine. Then abort if gt_pch_save finds an object with a marking routine but no swizzling routine. The swizzling routine would do something involving gt_pch_note_object and/or relocate_ptrs. Or maybe we would need two routines, one to note and one to relocate. Ian
