See scipy/scipy#21884 for a description and discussion and note that the developers said that this should be applied regardless of the compiler. I went back all the way to the first version of scipy where this particular file small_dynamic_array.h was added, and it already had the bug.

Testing

Tested with Intel oneAPI 2025.0.0 on Alma Linux.
