Memory Leaks for Simple Programs on Mac OS X

[dendisuhubdy]

See this (http://stackoverflow.com/questions/33657871/valgrind-c-memory-leak-in-empty-file?rq=1)

int main() { return 0; }
In the terminal, I run:

g++ -o temp.out temp.cpp
valgrind --tool=memcheck --leak-check=full --show-leak-kinds=all ./temp.out
This results in several memory leaks. How could this be?

==4438== LEAK SUMMARY:
==4438== definitely lost: 4,120 bytes in 2 blocks
==4438== indirectly lost: 2,288 bytes in 6 blocks
==4438== possibly lost: 8,336 bytes in 99 blocks
==4438== still reachable: 6,440 bytes in 13 blocks
==4438== suppressed: 5,020 bytes in 73 blocks
I have tried running other .cpp files and I get the exact same leak summary. About a month ago when I tried, nothing was wrong. I might have upgraded Xcode or something, if that could be the issue (?). These are my settings for g++:
