10.7 behaves like this:

dyld: loaded: /usr/X11/lib/libXdmcp.6.dylib
dyld: calling initializer function 0x95667700 in /usr/lib/libSystem.B.dylib
Bus error: 10

The one build on 10.6 (but run on the same 10.7 machine) does:

dyld: loaded: /usr/X11/lib/libXdmcp.6.dylib
dyld: calling initializer function 0x95667700 in /usr/lib/libSystem.B.dylib
dyld: calling initializer function 0x957090c0 in /usr/lib/libc++.1.dylib

and continues with the other initializers. So it seems that the crash really
occurs inside libSystem's initializer, which is the first to be called.
