Hi!
I just compiled a 64bit Valgrind 3.7 on OS X 10.7 hoping to use it for
a new project.
Wanting to try it out, I ran it on a project I just started that just
allocated and de-allocated a matrix (correctly) and it said that there
are weird leaks somewhere in the ImageLoader namespace/class belonging
do /usr/bin/dyld.
I've attached the leaky program and Valgrind's output below. To me it
seems that either OS X's dynamic linker leaks (which I find kind of
unlikely) or there is a bug in Valgrind.
Thanks,
Dan
#include <stdio.h>
int main()
{
printf("Hello World!\n");
return 0;
}
