Sadly neither do I. The patch however looks wrong to me. With the
patch applied, the code looks like this:
> offset = offsetof (prstatus_t, pr_reg);

So it seem that if core_signal has already been set (from a previous
thread ?) then it will not be overwritten. But the process ID will be
changed, so now you have a signal and a PID that do not match...
I can see why you would want to preserve the signal, but shouldn't you
also preserve the PID (and any other core related data) as well ? In
fact isn't this really a multithreading problem, with a single BFD
structure being used to represent multiple (potential) thread cores ?
Cheers
Nick
