I do get a test failure, although I'm not testing a function. 

I'm testing a system composed of various processes.

Will I get the error from the crashing process in the error log or in the terminal?

It's a pointless exercise if I do not.

Yes but I would be content with simply seeing the errors from crashing processes in the Common Test raw log file.

I get the output from my invocation of error_log:error_report, etc. but I do not see errors from crashing processes.

badarg? undef? Nowhere to be found and must be guessed.
