[LCP]/lib/ld-2.3.5.so unconditional jumps (valgrind / memcheck)

Hi

Apologies first : this is a C++ question, so I may be posting to the
wrong forum.

With Valgrind using memcheck, I frequently observe this:

==12443== Conditional jump or move depends on uninitialised value(s)
==12443==    at 0x1B8ECB13: (within /lib/ld-2.3.5.so)

Does anybody know :

what is /lib/ld-2.3.5.so ?
how do I fix this (does it need fixing?) ?

I'm using:

g++      version 3.3.6
valgrind version 2.4.0


This occurs even with 

//========
int main()
{ 
return 0;
}
//========

and you don't get more minimal than that!

I suppose I could ignore it - but we all know what happens when you just
cross your fingers and hope a problem will go away!

regards

Matt
