Comment (by knarf):

 It looks like IOUtil uses its own 'verbose' parameter (a keyword, and by
 that a string) during recovery of the parameters. String parameter
 pointers will/might get reset in that process, freeing their old pointers.
 The pointer in the GH is updated, but the copy made by CCTK_PARAMETERS
 inside the recovery routine itself is not. One of two solutions come to
 mind: either we make a copy of the whole string in this routine (and free
 it later), or we don't access parameters here directly, but always go
 through the GH.
