Errors in gdb6.4 "incomplete CFI data" and "const value length mismatch"

I am using gdb 6.4. I get a lot of errors like

>>During symbol reading, incomplete CFI data;
unspecified registers (e.g., 
>>rax) at 0x1452fa.

I also get errors like

>>During symbol reading, const value length mismatch
for '<some symbol>', 
>>got 8, expected 0.

>From reference to earlier discussions on this issue, I
noticed that 
complaints is set to 1 in .gdbinit.
I set it to 0 and these warning messages disappeared.

I had two questions in this regard :

1. Is it a wise thing to set complaints to 0 ?
Setting it to a huge value like "set complaints
20" gives me a huge set of 
the above warnings.

2. Can you let me know the exact cause for why the second
warning message 
appears namely
"during symbol reading, const value length...". I
assume that the first set 
of warnings related to CFI data is because registers if not
specified are 
incorrectly assumed as undefined.

It's not an error, just a warning.

I don't know what this one is.

I think it's perfectly fine - that's why it's the default.
