[Bug 2026834] Re: FTBFS: core dump during doxygen run

[Andreas Hasenack]

I went over the upstream git repo and cherry-picked commits to fix this.
There are many :/

It's probably less risky to update to 1.9.7.

I'll post this info in the debian bug too, see what the maintainer
prefers, before taking further action.

  This might also be a bug in doxygen. It didn't happen in the other arches build (which were done days earlier than amd64), and is also not happening in debian.

  From what I could see so far, in Ubuntu doxygen ends up calling dot,
  and dot errors with some file and exits. This exit status catches
  doxygen by surprise, and an atexit() handler crashes:

  Thread 7 "doxygen" received signal SIGSEGV, Segmentation fault.
