That's the message you have a variable that is uninitialised, and then you
try to jump to the "address" stored in that variable.  But since your
program works fine normally, I'd guess it's a Valgrind bug.  Can you
provide the full output from running with -v?  Better still, can you trim
down your program into a small example that triggers the error?

Thanks.
