 Ah, we quote different parts of "info reg".  I also get 
 
 (gdb) i r
 g0             0x0                 0
 g1             0x64                100
 g2             0x1                 1
 g3             0x0                 0
 g4             0xe5ea4acc          -437630260
 g5             0xe5ed4a90          -437433712
 g6             0x0                 0
 g7             0xe5ec6b58          -437490856

 for the inital breakpoint, but, significantly, it's the locals and
 inputs that are all messed up.  The static example you quote most
 likely fails for the very same reason, b/c you get junk instead of
 saved return address in %i7 (after window rotation), so it cannot do
 the proper backtrace.
