unknown warning when installing cd-hit, issue?

[Robvh-git]

During the building/install of CD-hit on PopOS, I get following warning:

In file included from cdhit-common.c++:28:

    inlined from ‘NVector<TYPE>::NVector(int, const TYPE&) [with TYPE = long int]’ at cdhit-common.h:119:10,

I've installed this numerously on Ubuntu and never receiver this warning., I recently switched to PopOS, which is a derivative from Ubuntu. It appears that the installation of CDHIT was succesful, but I'll test it soon.

However, what could cause this warning, as I've never seen it before? And could this jeopardize the functioning of CD-HIT?

I solved this issue replacing

items = (TYPE*)realloc( items, capacity*sizeof(TYPE) );


 with

items = (TYPE*)realloc(items, (unsigned int)(capacity * sizeof(TYPE)));
