ld: warning: pointer not aligned at address 0x1000218CF (RTTI$SYSTEM_$$_openchararray + 31 from /sw/lib/fpc/3.0.2/units/x86_64-darwin/rtl/system.o)

and many more.

The program works, but the warnings are a nuisance.

Rebuilding fpc from sources did not fix it, 3.0.2 or 3.1.1.

Also the same for i386-darwin.

I also tried to enforce alignment during rebuilding fpc with -Oa=16, but it did not fix it.

The compiler D seems to have the same issue: https://issues.dlang.org/show_bug.cgi?id=17289
