ADDITIONAL INFORMATION
This's the output of valgrind:

***
valgrind:  Fatal error at startup: a function redirection
valgrind:  which is mandatory for this platform-tool combination
valgrind:  cannot be set up.  Details of the redirection are:
valgrind:  
valgrind:  A must-be-redirected function
valgrind:  whose name matches the pattern:      strlen
valgrind:  in an object with soname matching:   ld-linux.so.2
valgrind:  was not found whilst processing
valgrind:  symbols from the object with soname: ld-linux.so.2
valgrind:  
valgrind:  Possible fixes: (1, short term): install glibc's debuginfo
valgrind:  package on this machine.  (2, longer term): ask the packagers
valgrind:  for your Linux distribution to please in future ship a non-
valgrind:  stripped ld.so (or whatever the dynamic linker .so is called)
valgrind:  that exports the above-named function using the standard
valgrind:  calling conventions for this platform.  The package you need
valgrind:  to install for fix (1) is called
valgrind:  
valgrind:    On Debian, Ubuntu:                 libc6-dbg
valgrind:    On SuSE, openSuSE, Fedora, RHEL:   glibc-debuginfo
valgrind:  
valgrind:  Note that if you are debugging a 32 bit process on a
valgrind:  64 bit system, you will need a corresponding 32 bit debuginfo
valgrind:  package (e.g. libc6-dbg:i386).
valgrind:  
valgrind:  Cannot continue -- exiting now.  Sorry.
***

The system used is Archlinux 32 bits.

Have the same result with Valgrind of the system and compiled from the source code. I'm use the source code of 3.24 with this line:

```
LD_LIBRARY_PATH=/opt/MV1/usr/lib/valgrind/lib/ /opt/MV1/usr/bin/valgrind
```

This error are persisted by years and appear from the 3.23 of valgrind.


==========================================
IT'S A BUG!!!! NOT RESOLVED!!!

my libraries already have debug info, even i compile it and use the new libraries with LD_LIBRARY_PATH=, and also export debug info and use ----extra-debuginfo-path=

NEVER WORK!!
