Maybe O5 is getting trashed by a trip through C2I or I2C adapters?  Could the throwing MH in question be getting called from compiled code maybe?

P.S. I just noticed that this comment a few lines above above isn't obviously correct:
  // save: Gargs, O5_savedSP

The call_VM_leaf macro probably trashes the G registers.  That only happens with -XX:+TraceMethodHandles, so it's OK for now.
