Ask HN: Is memory fragmentation with C still an issue?

1 points by Bambo ↗ HN
I'm looking to create a game in C++ using OOP extensively. One requirement is the use of references to handle objects. I have read that dynamic memory (new/mallo) causes heap fragmentation, i would like to know what the solutions are to the fragmentation, thanks!

It depends on the implementation of malloc. But usually yes, memory allocated at the same time is not at the same location. The solution is to allocate a big chunk at once and place your data in the order you want it. You can use, for example placement new for the objects and indices for references.

A problem with the chunk system is that i don't know how big a chunk is at the time it's declared?
