According to Johan, this bug was introduced by a pull kinke and I 
wrote to add support for a different real mangling on 
Android/x64, which broke your mangling that wasn't covered by the

It appears he is fixing both issues ATM. I suggest you either 
stick with LDC 1.12 as the compiler building DMD for now, or 
backport his eventual patch to LDC 1.13 if you can.
