In a new implementation of an ODE solver, we have a problem with memory allocations with Julia version 1.8.5:

1- With version 1.6.6, the memory allocations are correct, that is, they are constant and independent of the number of integration steps given.  
2- With version 1.8.5, the memory allocations are not correct, they increase with the number of integration steps given.

I have reviewed the code but I can’t find the error. Understanding that it is difficult for anyone to help us, we would appreciate any suggestions.

I am using DiffEqBase version v6.122.2 and the experiment to test memory allocations is in the following Github repository:  
[Memory Allocations Test](https://github.com/mikelehu/IRKGL_SIMD_NEW/blob/master/Experiments/Test%20memory%20allocations/Memory%20allocations%20test.ipynb)

Thanks in advance,  
M.
