mimalloc: warning: unable to allocate aligned OS memory directly

[ktlina]

Description of bug

When running metaspades.py, a "mimalloc" error rises. The run is correctly complete but only 30% of the total memory is used. Complete jobs require a very high amount of memoery in order to finish corrrectly, but then not all is being used.

So, what is your problem then?

There are no errors, just warning. The warning is benign, your OS failed to fulfill some allocation request, but SPAdes was able to workaround it.

PS: Memory consumption likely will be less with SPAdes 4.1

Closing as there is no issue here.
