SUMMARY
Link to the project file,
[https://github.com/nuxttux/Kdenlive_Crashes/tree/main/Render_Crashes]
Multiply_Demo_V1.
The render / export would consistently crash at different points in the
process.
I tried different render profile and it still crashed.
The one that worked was exporting as an image sequence, jpg.
STEPS TO REPRODUCE
1. Open project.
2. Enable Parallel processing.
3. Render / Export Project as MP4 or MOV
OBSERVED RESULT
.Export starts and crashed at some point with error message:
/usr/include/c++/14.2.0/bits/stl_vector.h:1130: std::vector<_Tp,
_Alloc>::reference std::vector<_Tp, _Alloc>::operator[](size_type) [with _Tp =
frei0r::param_info; _Alloc = std::allocator<frei0r::param_info>; reference =
frei0r::param_info&; size_type = long unsigned int]: Assertion '__n <
this->size()' failed.Rendering
.Or with error message:
corrupted double-linked listRendering
EXPECTED RESULT
For the render / export to complete.
