Так и должно быть - это же инструмент для отладки.  Без отладочных
символов использовать его очень неудобно - см. README_PACKAGERS:

-- Don't strip the debug info off valgrind.so or libpthread.so.
   Valgrind will still work if you do, but it will generate less
   helpful error messages.  Here's an example:
 
   Mismatched free() / delete / delete []
      at 0x40043249: free (vg_clientfuncs.c:171)
      by 0x4102BB4E: QGArray::~QGArray(void) (tools/qgarray.cpp:149)
      by 0x4C261C41: PptDoc::~PptDoc(void) (include/qmemarray.h:60)
      by 0x4C261F0E: PptXml::~PptXml(void) (pptxml.cc:44)
      Address 0x4BB292A8 is 0 bytes inside a block of size 64 alloc'd
      at 0x4004318C: __builtin_vec_new (vg_clientfuncs.c:152)
      by 0x4C21BC15: KLaola::readSBStream(int) const (klaola.cc:314)
      by 0x4C21C155: KLaola::stream(KLaola::OLENode const *) (klaola.cc:416)
      by 0x4C21788F: OLEFilter::convert(QCString const &) (olefilter.cc:272)
 
   This tells you that some memory allocated with new[] was freed with
   free().  If valgrind.so was stripped the message would look like
   this:
 
   Mismatched free() / delete / delete []
      at 0x40043249: (inside valgrind.so)
      by 0x4102BB4E: QGArray::~QGArray(void) (tools/qgarray.cpp:149)
      by 0x4C261C41: PptDoc::~PptDoc(void) (include/qmemarray.h:60)
      by 0x4C261F0E: PptXml::~PptXml(void) (pptxml.cc:44)
      Address 0x4BB292A8 is 0 bytes inside a block of size 64 alloc'd
      at 0x4004318C: (inside valgrind.so)
      by 0x4C21BC15: KLaola::readSBStream(int) const (klaola.cc:314)
      by 0x4C21C155: KLaola::stream(KLaola::OLENode const *) (klaola.cc:416)
      by 0x4C21788F: OLEFilter::convert(QCString const &) (olefilter.cc:272)
 
   This isn't so helpful.  Although you can tell there is a mismatch,
   the names of the allocating and deallocating functions are no longer
   visible.  The same kind of thing occurs in various other messages
   from valgrind.
