creating it again later with the same preallocate.
Anyway it works with MatDuplicate for now.

There is also the hedge of adding a parameter and API function to control
which of these two behaviors is used, and if trying to preallocate twice,
throwing an error that instructs the user how to change the behavior,
noting that it will increase peak memory usage.

Thanks for tracking this down. Is there a reason to prefer preallocating twice
