Please try building libphobos and libdruntime with -fno-section-anchors.
You certainly need to do this, but -O0 means that section-anchors
optimization is turned off anyway, so that isn't actually your problem.
Judging by:
https://bitbucket.org/goshawk/gdc/issue/120/fsection-anchors-broken-on-arm
(specifically
https://bitbucket.org/goshawk/gdc/issue/120/fsection-anchors-broken-on-arm#comment-686378),
I thought that was fixed.
I guess not. I'll build it with no-section-anchors from now on.
Can you run `disassemble` in gdb to see what the faulting instruction is?
