   2 the liburcu libraries. This information is extracted using libabigail

   5 The artefacts used to generate these were built with CFLAGS="-O0 -ggdb" on an
   6 Ubuntu 18.04 x86_64 system.

   9 changes. For example, here we compare an in-tree built version of
  10 liburcu-memb.so with the serialized ABI of stable-0.13 :
