Icinga2 crashes after a few seconds when starting dashing-icinga2

[elpito]

Hi,
After upgrading from Fedora 27 to 28 Icinga2 crashes, when I start dashing-icinga2. Because of distribution changes, I had to update the rubygem thin-1.6.4 to thin-1.7.2 (made the changes in Gemfile.lock). This is the error: /usr/local/share/gems/gems/thin-1.6.4/lib/thin/server.rb:107: warning: constant ::Fixnum is deprecated

The problem is reproducible, I just have to start dasing-icinga2.

This is the message in systemd, when icinga2 crashes:

icinga2[1392]: /usr/include/c++/8/bits/unique_ptr.h:328: typename std::add_lvalue_reference<_Tp>::type std::unique_ptr<_Tp, _Dp>::operator*() const [with _Tp = icinga::Expression; _Dp = std::default_delete<icinga::Expression>; typename std::add_lvalue_reference<_Tp>::type = icinga::Expression&]: Assertion 'get() != pointer()' failed.

Here the crashreport:

Hi,

that's a problem with Icinga 2 then, nothing related to this project which just sources the API.

Cheers,
Michael

[elpito]

Thank you, should I place this in the Icinga2 project? I thought, because it's only happening, when enabling the dashboard, it should be placed here.

Cheers,
Daniel

This has been reported already IIRC, I've fixed a similar thing for Icinga 2.9.2.
