--- Comment #32 from Dr. Werner Fink <werner at suse dot de> ---
For me it looks like a problem with (lib)sqlite3 and its memory managment a=
nd
libmemusage.so

35108
35109     if( new_ht=3D=3D0 ) return 0;
35110     sqlite3_free(pH->ht);
35111     pH->ht =3D new_ht;
35112     pH->htsize =3D new_size =3D sqlite3MallocSize(new_ht)/sizeof(stru=
ct _ht);
35113     memset(new_ht, 0, new_size*sizeof(struct _ht));
35114     for(elem=3DpH->first, pH->first=3D0; elem; elem =3D next_elem){
35115       unsigned int h =3D strHash(elem->pKey) % new_size;
35116       next_elem =3D elem->next;
35117       insertElement(pH, &new_ht[h], elem);
(gdb) print new_ht
$8 =3D (struct _ht *) 0x1ba9330
(gdb) print *new_ht
$9 =3D {count =3D 0, chain =3D 0x0}
(gdb) print new_size
$10 =3D 4293843945
(gdb) print pH->htsize
$11 =3D 0
