I am using the latest apt packages on Ubuntu 18.04.6:
- Boost 1.65.1
- valgrind-3.13.0
Here is the test file; it intentionally doesn't include any tests:
// temp.cpp
#define BOOST_TEST_MODULE some_name_here
#include <boost/test/included/unit_test.hpp>
The source is compiled then linked like this (dumped from cmake):
/usr/bin/clang++-12 -O3 -DNDEBUG -Wall -Wextra -O0 -g -std=gnu++17 -o temp.o -c temp.cpp
/usr/bin/clang++-12 -O3 -DNDEBUG temp.o -o temp /usr/lib/x86_64-linux-gnu/libboost_unit_test_framework.so
I invoke valgrind on the executable:
valgrind --leak-check=full --show-leak-kinds=all --track-origins=yes --verbose --log-file=valgrind-out.txt ./temp
Which yields this error log:

Why is this leaking?
Here is what I have tried so far:
I noticed that using the static library in the link command fixes the leak, by replacing libboost_unit_test_framework.so with libboost_unit_test_framework.a, however this doesn't explain why this is happening.
Thanks.
