The classical explanations for the above are:
1. the application is statically linked
2. the application is using an alternate malloc library
(e.g. tcmalloc or jemalloc or ...)
3. the dynamic loader does not support LD_PRELOAD
For 1 and 2, you can use --soname-synonyms=... to indicate to
valgrind that the malloc lib is static or in which soname it is found.
For 3, you have to find (or recompile) a dynamic loader
that supports LD_PRELOAD.
