No, same problem. BTW, it's segfaulting in _d_dso_registry()

4. If you make any other calls into the stdlib aside from
I/O, do they
work?
It doesn't matter. The following program segfaults:
void main() {}
5. Does gdb reveal anything interesting?
Unfortunately there's no debugging symbols in
_d_dso_registry(). I
assume the compiler is writing asm directly.

I got a similar issue when upgrading to 2.063 on arch linux, so
I feel this may be relevant to the current problem. Heres the
backtrace for me.

Unfortunately, no debugging symbols for phobos.
program was compiled with dmd (2.063) using the following
flags: -g -debug -unittest
I suspected it may be the problem with shared libraries.
Can you try compiling that hello world with static libphobos?
Or can you attach your segfaulting binary?
