It fixed the problem. Valgrind now detects the lost memory.
Thank you very much for your help.

There were other places where this string was used:

frank@linux:~/valgrind> find -type f | xargs grep libcZdsoZd6 | grep -v svn |
grep -v Binary
./coregrind/m_redir.c:     _vgi_libcZdsoZd6__ZdlPv  -->  libc.so.6:_ZdlPv
./coregrind/m_replacemalloc/vg_replace_malloc.c:         return
VG_REPLACE_FUNCTION(libcZdsoZd6,malloc) (new_size); \
./coregrind/m_replacemalloc/vg_replace_malloc.c:
VG_REPLACE_FUNCTION(libcZdsoZd6,free)(ptrV); \
./coregrind/m_replacemalloc/vg_replace_malloc.c:      return
VG_REPLACE_FUNCTION(libcZdsoZd6,memalign)(VKI_PAGE_SIZE, size); \
./coregrind/m_replacemalloc/vg_replace_malloc.c:      mem =
VG_REPLACE_FUNCTION(libcZdsoZd6,memalign)(alignment, size); \
./memcheck/mac_replace_strmem.c:#define  m_libc_so_6             libcZdsoZd6
            // libc.so.6

Can/Should i also do a simple replace on these?
