We will try this and inform you about the results.

For one child process we checked, how many allocated fragments had not 
been freed:

[...]
173  ->  mk_action(106)
237  ->  addstr(787)
3277  ->  pv_parse_ht_name(121)
3361  ->  pv_parse_format(727)

So we had a look at pv_parse_ht_name() and we wonder, wheter the 
variable hpv is freed. Before "return 0" it is used but not freed. 
Additionaly the return from pv_parse_format() (&hpv->pve) seems not to 
be freed.
Could this be the problem?

Christian
