Crashing in Rocky 9 about rendermanforblender

[flipphillips]

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 :)

Added note - awkwardly debugging with VScode, I noticed that it appears to crash in attach of class RfBStatsManager(object):

Right where it starts to try to join

       self.boot_strap_thread = threading.Thread(target=self.boot_strap)
        self.boot_strap_thread.start()
        # wait 5 seconds
-> -> ->        if not self.boot_strap_thread.join(5.0):
            # boostrap thread didn't stop, abort
            self.kill_boostap_thread()
