Looks like UE4Editor overrides some C++ memory allocation APIs, which breaks LLVM.
This still happens in current git (dd072cf4b1) with unreal editor 4.16. Kernel 4.12.3-ARCH Rx 480 libdrm-2.4.82 Full log output from two runs. One with default binned2 malloc and one with ansimalloc: https://pastebin.com/tmCAaEkX

Screenshost are from version 4.17 after the editor startup freezed my desktop. Only mouse worked.
Not likely to be a radeon bug, but here is a possible solution for UE4 4.16: 17:18 <@rcl> if 4.16, remove the linker script 17:18 <@rcl> and try again 17:19 <@rcl> drivers aren't siloed from our new/delete and are probably allocating memory through UE, a user program (see LinuxToolChain.cs) If someone can try that and report, that would help.
I tested with the current promoted branch (which has the linker script commented out by default). This gives me a complete desktop freeze like Thomas Kowaliczek already reported.
The freeze problems are very likely this issue: https://bugs.freedesktop.org/show_bug.cgi?id=101977 I haven't seen this allocator problem in 4.16 with ubuntu 16.x, I suspect it's tied to a clang / libstdc++ / distribution combo.
