Assertion failed: "iter != m_map.end() : Non-existent property removed from graph"

Hi,

I converted my bound callables to bindless callables in OptiX 6.0, and I got 20% faster in a test scene, which is great. However, if I set to a different group of programs (any hit, closest hit and bindless callables) at runtime, I got error:

Unknown error (Details: Function “_rtVariableSet1i” caught exception: Assertion failed: “iter != m_map.end() : Non-existent property removed from graph”, file: , line: 147)

This message doesn’t make much sense to me. What does it mean?
Any help or information may help me to narrow down the problem.

Thanks

Would you be able to send a minimal reproducer for this case via e-mail?
Please rename attachments with *.zip extensions to something else, *.zi_ will do.
