Bug 23517 – dmd with -g flag fails to link on macOS with unaligned pointer

It looks like Apple's linker is getting tighter on what it will allow: ~/dlang/dmd-2.101.0/osx/bin/dmd -g hello.d ld: warning: alignment (1) of atom 'anon' is too small and may result in unaligned pointers ld: warning: alignment (1) of atom 'anon' is too small and may result in unaligned pointers ld: warning: alignment (1) of atom 'anon' is too small and may result in unaligned pointers ld: warning: alignment (1) of atom 'anon' is too small and may result in unaligned pointers ld: warning: alignment (1) of atom 'anon' is too small and may result in unaligned pointers ld: warning: alignment (1) of atom 'anon' is too small and may result in unaligned pointers ld: warning: alignment (1) of atom 'anon' is too small and may result in unaligned pointers ld: warning: alignment (1) of atom 'anon' is too small and may result in unaligned pointers ld: warning: alignment (1) of atom 'anon' is too small and may result in unaligned pointers ld: warning: alignment (1) of atom 'anon' is too small and may result in unaligned pointers ld: warning: alignment (1) of atom 'anon' is too small and may result in unaligned pointers ld: warning: pointer not aligned at address 0x10007023A ('anon' + 570 from hello.o) ld: warning: pointer not aligned at address 0x100070257 ('anon' + 599 from hello.o) ld: warning: pointer not aligned at address 0x100070347 ('anon' + 839 from hello.o) ld: warning: pointer not aligned at address 0x100070382 ('anon' + 898 from hello.o) ld: warning: pointer not aligned at address 0x10007039E ('anon' + 926 from hello.o) ld: warning: pointer not aligned at address 0x1000703D6 ('anon' + 982 from hello.o) ld: warning: pointer not aligned at address 0x100070429 ('anon' + 1065 from hello.o) ld: warning: pointer not aligned at address 0x100070459 ('anon' + 1113 from hello.o) ld: warning: pointer not aligned at address 0x100070475 ('anon' + 1141 from hello.o) ld: unaligned pointer(s) for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) Error: linker exited with status 1

According to a post on the forums [1], this can be worked around by setting the environment variable `MACOSX_DEPLOYMENT_TARGET=11`. [1] https://forum.dlang.org/post/[email protected]
