description

Rendering crashes blender in Rocky 9 hard w/ core dump

to replicate

1, Launch blender 4.1
2. Enable RenderMan plugin
3. Context menu "Use RenderMan"
4. Attempt to IPR to anything

expected

Render!

actual

❯ blender
Read prefs: "/home/flip/.config/blender/4.1/config/userpref.blend"
***  abort: due to uncaught exception  ***
zsh: IOT instruction (core dumped)  blender

regression

• prman works from cmd line
• prman add-ins for Houdini and Katana work
• tried earlier / dev versions of plugin from GitHub
• tried a few commits before release
• tried different blender builds

One additional note, if I run it in

blender --debug

it crashes on exit if the RenderMan plugin is even enabled. Doesn't even need to be invoked.

Hi Filip,

This is just a guess but I have a feeling this due to ABI std::string incompatibilities. It definitely crashes for me when using Blender 4.1 with the current version of RenderMan 26.0, on an RHEL9 instance. However, it works as expected when using our in progress RHEL9 build of RenderMan.

I would try this again when the RHEL9 build comes out (slated for 26.2).

OK - that makes sense. Strings - always strings. My Pascal ray tracer in the '80s - strings. Convert that code to C in the 90s - strings. Strings!!!

Feel free to put me on the external beta list again for that build :)
