Memory leak or valgrind too touchy ?

Hi

I am wondering if there is a memory leak in libCint & libCore as compiling an empty program :

int main(int argc, char *argv[])
{
}

linked with root-config --libs (tested with v4.00.0 & 4.04.2) give me the report below (lastest stable valgrind). Does this leaks are due to miss behavior or interpretation of valgrind or is there true memory link in related root lib ?

Thx for you comment on this.
