If one of the libraries is compiled with tcmalloc then the latter will add GLIBCPP_FORCE_NEW and GLIBCXX_FORCE_NEW to environment at startup and thus break commandtest.
How are they getting those envs into our environment after we clean it out ? We strongly aim to prevent any non-whitelisted env variable leakage into children we spawn, so I would really like to kill these env vars instead of changin the test.
They inserted at process startup I guess [1]. They are cleared out by commandtest but visible in commandhelper.
Hmm, so is comandhelper getting linked to tcmalloc by mistake then ? If so, how easy is it to stop it being linked
It is not liked directly. In my case the chain is libdevmapper.so -> libudev.so -> libtcmalloc.so. It is distro specific but I guess other can step across this issue and for a different chain. One just need to link on of the libraries libvirt uses to tcmalloc.
Ah I see. I think this smells like a bug in the tests/Makefile.am
Ahh, this is fixed upstream already by eae746b2d the way you suggest ))
