A bit OT: git - ridiculous memory requirements

[Vaclav Mocek]

Hi all,

I have a cloned GCC git repository, on PC with 1.5GB of RAM and 3GB swap.

When I run "$git gc --aggressive", I will get after few hours an error:

$ git gc --aggressive
Counting objects: 1332887, done.
Delta compression using up to 2 threads.
fatal: Out of memory, malloc failed (tried to allocate 4838335 bytes)
error: failed to run repack
$

4.5GB of memory is not enough, what is that?

I wonder what git is internally doing, it seems to me as a pretty
non-optimal implementation. It is the first application I have which has
been killed by OOM killer.

The size of .git directory is >900MB.
