[Halld-offline] collisions among static and dynmaic (plugins) libraries

[Richard Jones]

Hello Dave,

I have run into a nasty problem with segfaults at program exit. This seems
to be related to the appearance of duplicate instances of some classes (eg.
DEventWriterREST) that are defined both in the plugin (danarest.so) and the
static library that is linked into hd_root (libHDDM.a). What is your policy
with regard to classes that are used both in the static library and in the
base code?

BTW there is the related question of why the DEventWriterREST is duplicated
in two places in the tree, once in the Utilitiles/plugins/danarest and once
in the libraries/HDDM area.
