This is a production release to fix three bugs, none of which affects well formed scripts on FreeBSD: The first bug is that bc/dc will exit on macOS when the terminal is resized. The second bug is that an array, which should only be a function parameter, was accepted as part of larger expressions. The third bug is that the value stack for dc was cleared on any error. However, this is not how other dc behave. To bring dc more in line with other implementations, this behavior was changed. This change is why this version is a new major version. (cherry picked from commit 54d20d67e2af28d948ce2df13feb039fa10900fc) MFC after: 3 days (cherry picked from commit 12e0d316644a4f80f5f1f78cf07bd93def43b1ca)
