<div dir="ltr">Thanks for all of the replies regarding this.<div><br></div><div>I understand that the current instability makes determining what's a user error versus an implementation error difficult, and don't want to be a pest about it. In this particular case, I went by the responses that I had seen in my search for this error (i.e., it was an error in the user's code), and asked from that perspective. In hindsight, I guess it would have helped if I had sent the code. :)</div>

r10236 fixed a bug in the currency-converter example in 1.2 (a method<br>
that was implicitly defined to return :id returned NIL.) The same<br>
bug's in the trunk, but the error that Chris is seeing seems to be<br>
occurring during ObjC (re)initialization, long before we get to that<br>
point.<br>
<br>
r10246 fixed a bug in the kernel code that caused the frame pointer<br>
register to be restored incorrectly when PROCESS-INTERRUPT returned.<br>
that often led to a segfault and general wackiness.<br>
