If I change char[] to int[], it works.

_d_arraysetlength2 should be defined in the new libphobos.a. Make sure 
the new one is installed over the old one.

Ah, I had forgotten about libphobos.a in /usr/lib.  Indeed, this was the cause.

Thank you.

I can't replicate this issue. Did you rebuild Phobos or are you trying
to use GDC's GPhobos in combination with DMD?
