strange link error: _My_struct__xtoHashFNbNeKxSQBlQBoQBiZm _My_struct__xopEqualsMxFKxSQBlQBoQBiZb

[Richard (Rikki) Andrew Cattermole]

xtoHash and xopEquals are generated by the compiler automatically.

Curiously those two symbol names are not demangling.

Given this, I suspect the best thing to do is file a bug report with ldc 
with the code that generated the linker error.
