Haiku building in macOS enviroments result in clang's segfault

[rafaga2k]

Building HAiku using instructions on ​https://www.haiku-os.org/articles/2015-02-05_building_haiku_mac_os_x_1010_yosemite/ results in segfault 11 in the clang compiler LLVM

Xcode 8.3.3 Build version 8E3004b (macOS 10.12.5)

This is a bug from Apple's (Clang compiler LLVM), not from Haiku, i report this to put a warning into the Haiku page to MacOSusers that want to copile Haiku.

i attach the resulting output from compiling:

As you say, compiler crashes in other's compiler are not Haiku's fault. Such warning messages do not have a place on the bugtracker, maybe use the forum instead. Closing as invalid then, but thanks for the heads-up!

[phoudoin]

My bad, it was me who suggest him to file a bug report. While it's not on Haiku to fix the bug itself, Apple won't update itself the "Building Haiku on macOS" guide either.
