> There are thread unsafe access that result in race condition that occur during concurrent execution of JIT_compile_method_with_params function.
> Build configuration - debug
> Write -> Read and Write -> Write data-races
> Memory read at "drljitinterface.cpp":250 conflicts with a prior memory
> write at "drljitinterface.cpp":250 (L250: int current_nb = method_seqnb++;)
