in reply to GDB journey into perl internals

I've never used GDB. Does it allow you to place watch statements on breakpoints? If so, and if the address of the unreference scalar is consistant, then put a breakpoint on the return statement from malloc with a watch looking for the breaking address. That should allow you to backtrack to the routine that allocates the SV.

    Good idea! That remembers me my soft-ice sessions of many years ago :-)
    I just don't know how to do that in gdb. Of course, I should RTFM. Maybe I should try ddd once again...
