warning: pointer not aligned at address

[Andrew Edwards via Digitalmars-d-learn]

When compiled with any dmd compiler from 2.069.0 through present 
(2.074.0), https://rosettacode.org/wiki/100_doors#D produces the 
following linker warning:

ld: warning: pointer not aligned at address 0x10004FCEB 
(_D51TypeInfo_S3std5range13__T4iotaTiTmZ4iotaFimZ6Result6__initZ 
+ 24 from doors100.o)

[65 other lines removed for brevity]

ld: warning: pointer not aligned at address 0x100050C7D 
(_D11TypeInfo_xb6__initZ + 16 from doors100.o)

specific compilers checked:
dmd-2.068.0	dmd-2.068.1	dmd-2.068.2	dmd-2.069.0	dmd-2.070.0	dmd-2.071.2	dmd-2.073.1	dmd-2.073.2	dmd-2.074.0

What's the proper way to address these warnings? The code is 
linked and works as expected but, to me, there is just something 
about those warnings that cries out for attention.

Is there something I can do to align this code or is this 
something that needs to be addressed in the compiler?

Thanks,
Andrew
