I tried building dmd on my machine but irstate.h is missing from the zip file.

No problem, I already found something. The +4 offset is wrong it should be +8
because it's the length field of rt.util.container.Array(T) and on X86_64 the
pointer before it is 8 byte.

Also the rest of your asm slightly differs from mine. So either we're not linking against the same library or your linker rewrites code (LTO?).

Good, I'm glad I'm not undergoing severe hallucination :-)

Additional data - the following gives me a working program:

dmd -c junk.d
copy junk.o libphobos2.a to centos6.4 x86_64 machine
on centos6.4, link using gcc link line given by dmd -v junk.d

Also, the stdio bits are a red herring.  The following also segfaults:
