>Description:
Debugging any simple hello world program:
with mi on gdb-5.3:

(1) some registers number are not recognized
    even if data-list-register-names show them.
(2) after more then 2 -data-list-register-values
    gdb starts misbehaving.

log follows:

-data-list-register-names
^done,register-names=["eax","ecx","edx","ebx","esp","ebp","esi","edi","eip","eflags","cs","ss","ds","es","fs","gs","st0","st1","st2","st3","st4","st5","st6","st7","fctrl","fstat","ftag","fiseg","fioff","foseg","fooff","fop","xmm0","xmm1","xmm2","xmm3","xmm4","xmm5","xmm6","xmm7","mxcsr","orig_eax","mm0","mm1","mm2","mm3","mm4","mm5","mm6","mm7"]
