I tried cooking my project on linux using the editor, unreal front end and directly running UE4Editor -run=Cook ...
and all of them failed to cook the project. The actual cooking succeeds but the engine crashes afterwards making the tools think that the cooking failed.

I’m using the release branch. Fedora 23, clang 3.8.
I can run my project just fine, so I don’t think those are the issue.
Using gdb I get the following callstack for the crash:

Which looks like it might be caused by a static FText object that is being deleted after jemalloc cannot be used anymore.
Here’s the core file from the gdb session
There doesn’t seem to be any easy workaround, so I guess I can’t run servers on linux.
Edit: Using -ansimalloc gets rid of the error. Which again hints that this is caused by using jemalloc after it has been shut down.
I can now cook my project from the command line, but not from the editor, with this command:
./UE4Editor -run=Cook -ansimalloc -unattended -TargetPlatform=LinuxNoEditor "/path/to/project/Project.uproject"
