--- Comment #11 from Jürgen Reuter <juergen.reuter at desy dot de> --- The ICEs are indeed with that problem. (Duplicate ticket https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83042) However, now I get segfaults however in several of our C and C++ bind(C) interfaces. I do not know whether this is at all related to this here. Will try to isolate the other thing, however, that will not work without also shipping C code.
