Hello.

I have encountered std::overflow_error again.

I am using robin hood version 3.10.0.

This time I cannot create test case. I hope you can give me guidelines to find source of problem. I am working with robin_hood::unordered_flat_set<int32_t>. My application is working with 200 containers and 10 million elements in total, so I cannot find good way to create test example. It takes about 5 minutes of number crunching before application crashes while trying to insert that specific integer into that specific container.

My application is basically doing this:

• Create 200 containers.
• Do work with all containers (container::insert, container::erase, container::clear). This work takes about 5 minutes.
• At some moment, application has to process some problematic container.
• Problematic container contains some elements.
• I know what are new elements that must be inserted into problematic container.
• Problematic container is cleared before insertion.
• New elements are inserted into problematic container one-by-one. Insertion fails with std::overflow_error after some number.

Exception is not thrown if I recreate standalone test case with same elements.

Thanks.
