Debugging an application compiled with GCC 3.4 (experimental) produces warnings 
that register information is out of range.  For example:

$ gdb-5.3 cc1
(gdb) break store_bit_field
During symbol reading, register number 208 too large (max 72) in symbol target.
During symbol reading, register number 208 too large (max 72) in symbol 
unsignedp.
(gdb) break emit_move_insn
During symbol reading, register number 1244 too large (max 72) in symbol 
unsignedp.
During symbol reading, register number 1244 too large (max 72) in symbol type.
During symbol reading, register number 1244 too large (max 72) in symbol 
alias_set.
