Thanks for the hint. On OpenSolaris/amd64 for Sol10u3 I get Unhandled  
Exception 0x10, PC 0x0, NPC 0x4.

This is what gdb says on OSX/ppc after the above register dump:

Program received signal SIGABRT, Aborted.
0x926daaf0 in __kill ()
(gdb) bt
#0  0x926daaf0 in __kill ()
#1  0x92775bb0 in abort ()
#2  0x000b5308 in ?? ()
#3  0x000febe8 in ?? ()
#4  0x000febe8 in ?? ()
Previous frame identical to this frame (gdb could not unwind past this  
frame)
(gdb)

Doesn't look too useful.
