Difficult to say without more information.
It is not abnormal to have new partially defined bytes created,
then transformed to fully initialised bytes, and then GC-ed.

This might be a consequence of a bug in your program, likely :)
Or it might be a bug in Valgrind, less likely :).

You can use gdb+vgdb to see what your program is doing under Valgrind,
and e.g. see if/where/why it is looping and/or what it is doing.
