Starting with Glibc 2.23, Glibc messes around again with symbols. Basically the dyn. linker expects that every dyn. linked executable is linked against glibc. If you don't do so, calloc is missing: e.g. ./tw12704b: symbol lookup error: ./tw12704b: undefined symbol: calloc, version GLIBC_2.2.5

Anybody looked already into it and worked out a solution? Always linked against glibc is out of question.
