Does anyone have any insights into why clang ICEs when
compiling layer2/RepCylBond.cpp in pymol at any optimization higher than
-O0 on darwin?
https://bugs.llvm.org/show_bug.cgi?id=37280
The problem is suppressed with -fno-strict-aliasing so I am wondering if
there is some code in that file that could be re-organized to avoid the
bug. Unfortunately, the ICE doesn't seem to indicate what line in the
source file triggered the compiler segfault.

ps Oddly the same reproducer seems to not trigger the issue on x86_64
ubuntu bionic Linux.
