Hi,
Just to know if someone else has the same issue:
OS X 10.10.1 Xcode 6.1 (6a1052d)
cc --version Apple LLVM version 6.0 (clang-600.0.54) (based on
LLVM 3.5svn)
DMD is builded just fine:
DMD64 D Compiler v2.067-devel-e17631e
But the dmd crash on building druntime:
semantic3 treap
semantic3 ti_AC
semantic3 ti_Acdouble
semantic3 ti_Acfloat

I get the same. Two separate dustmite reductions got me

https://issues.dlang.org/show_bug.cgi?id=13788
I suspect it's showing up because of building with clang. IIRC it
only happens if you build a release version of the compiler.

A few years back, clang was generating an invalid copy ctor for a struct in DMD. I assume this has long since been fixed, but clearly clang still has a few bugs.

I generated a debug build though and it works fine. So it sounds like a codegen bug to me, but I haven't taken the time to try and figure it out. The crash I saw was in a ctor though. If it's anything like the crash I saw back when OS X was moving to clang, it will be that the "this" pointer has a bad offset.A few years back, clang was generating an invalid copy ctor for a struct in DMD.
