Dears
Valgrind reports me something shown below.
==1193== Invalid read of size 1
==1193== at 0x4023694: strcpy (in
/usr/lib/valgrind/x86-linux/vgpreload_memcheck.so)
==1193== by 0x41D8837: (below main) (in /lib/libc-2.5.so)
==1193== Address 0x42F1455 is 13 bytes inside a block of size 15 free'd
==1193== at 0x4020FEC: operator delete(void*) (in
/usr/lib/valgrind/x86-linux/vgpreload_memcheck.so)

We need self-contained, minimal code, before taking any further action. Thanks.

For just an example of user-code error leading to a valgrind message mentioning
std::string::_Rep::_M_destroy, see:
http://linux.derkeiler.com/Newsgroups/comp.os.linux.development.apps/2006-02/msg00070.html
That's why, missing a small self-contained snippet, this PR will be closed.
