Hi, I was debugging a program compiled with `mpicxx` and noticed that when the program is being launched the `_init` function gets called multiple time, once for each library linked. For example, in my case I see that it gets called from all these libraries:
_init () from libopen-pal.so.40 _init () from libopen-rte.so.40 _init () from libmpi.so.40 _init () from libmpi_cxx.so.40 My example program uses OpenMP, so because of the call to `_init` for each library the runtime gets initialized 4 times. Is this `_init` function a constructor for each one of this libraries? What does it actually do? I couldn't find it in the OpenMPI source. Thank you!
