- previously used a Pstream::exit() invoked from the argList destructor to handle all MPI shutdown, but this has the unfortunate side-effect of using a fixed return value for the program exit. Instead use the Pstream::shutdown() method in the destructor and allow the normal program exit codes as usual. This means that the following code now works as expected. ``` argList args(...); if (...) { InfoErr<< "some error\n"; return 1; } ```
