Hello List, I'm seeing lots of reports similar to the ones attached below when I run valgrind on my project. The code seems to be sound because when I don't dlopen a shared library, no reports are output. Also, I'm unsure if it is relevant but my project uses boost.
What, in your opinion, is causing valgrind to report the (non-)issues below? And, if it is indeed valgrind at fault here, are there any special measures I can take so as to ensure valgrind runs correctly? ================= ==20245== Invalid read of size 4 ==20245== at 0x58E064D: ???
