I do not see how watchpoints might help here? The vptr should probably be modified (set to 0), when the GC frees it, but gdb shows that it still points to the vtable. I think the possibility that bdwgc has a bug in sweep is quite small, since the other code (OS,compiler,runtime) is much less mature. This means somewhere a vptr is stored into already-freed memory. _______________________________________________ Gc mailing list Gc-V9/[email protected] http://www.hpl.hp.com/hosted/linux/mail-archives/gc/
