sorry, i still don't understand.

in the case where you have 3 frames:

3 [ sighandler ]
2 [ sig frame  ]
1 [ try-catch  ]

if the signal is triggered from the try-catch frame, and an exception is
thrown from the sighandler, how many times is uw_frame_state_for()
called? 

i should mention that this case doesn't work on x86 either (with
g++-3.3). it works for libjava because there is always some more frames
between try-catch and the signal frame.

thanks,
