Я нашел это Гист пару дней назад. Я немного адаптировал его в своем репозитории проекта CMake и обнаружил странное поведение: он корректно работает только под valgrind. Ничего не печатается, когда работает нормально или под GDB. Я думаю, что это состояние гонки, но не могу его выяснить. Кто-нибудь может помочь в этом исследовании?
Вальгринд печатает:
/usr/bin/valgrind --tool=memcheck --xml=yes --xml-file=/tmp/valgrind --gen-suppressions=all /home/fiorentinoing/devel/libuv_tls/cmake-build-debug/test/bin/libuv_tls
