I get the above error whether I use the flag "-Wno-argument-outside-range" or
not, or using other flags to try and suppress this error (ex
"-Wno-error=argument-outside-range" or "-w"). The header file (operators.h in
the above sample) has a check for a 0 bound, so this code should be able to
compile and run safely.
Is this a bug, or is there perhaps another way clang should be configured to
suppress errors of this type?
