Description Andrew Pennebaker 2017-03-16 16:29:30 UTC

I'm trying to hunt down memory leaks in librdkafka. However, when I try to valgrind a minimal example application, Valgrind often aborts, complaining about some kind of "Invalid read of size 8".

Alpine 3.5 + Valgrind 3.12:

Debian Jessie + Valgrind 3.10:

To work around this issue, you should link the rdkafka application dynamically.

Even if we fix the bug you reported, valgrind will not be able to recognize memory allocations in a statically linked application, so it will not be useful for discovering memory leaks.
