Vaporizer2-lv2 crashes Ardour 9.2

#1

As soon as I insert vaporizer2-lv2 (3.5.0-2), Ardour 9.2.326 crashes immediately.
(vst3-version working).
(Same issue in Qtractor, Working in Reaper)
CashyOS, Kernel 6.19.11-1

#2

Works fine here with ardour-9,2.308 and ardour-9.2 openSUSE build.

#3

Terminal Output:

/usr/include/c++/15.2.1/optional:1186: constexpr _Tp& std::optional<_Tp>::operator*() & [with _Tp = juce::AudioPlayHead::PositionInfo]: Assertion 'this->_M_is_engaged()' failed.

No problem here either.
I’m using a self-compiled ardour-9.2-129 and self-compiled Vaporizer2-3.5.0-11 in Ubuntu 22.04.

I presume you’re using CatchyOS’ versions of Ardour and Vaporizer and in that case you should file a bug report with them.
“Assertion ‘this->_M_is_engaged()’ failed” errors appear to be c++ related so maybe they’ve compiled Vaporizer and Reaper against one libc++ and Ardour and Qtractor against another one, and that’s why the Reaper combo works but the other ones fail.
