It seems that dmd silently accepts simultaneously -m32 and -m64 and generates code according to last option. void main() {} With -m32 -m64 it produces x64 and with -m64 -m32 it produces x86. It either should issue a warning or error.

As mentioned in the PR open by @woframw, this is actually not something we want. It's a common behavior of CLI to allow args to be overridden, and just take the last one into account. We have some switch that follow this behavior already (checkaction), and we rely on this behavior in our testsuite. Closing as WONTFIX.
