Can you do M-x trace-function-background RET call-process-region RET,

1 -> call-process-region: start=1 end=77 program="/usr/sbin/sendmail" delete=nil buffer=0 display=nil 
args=("-oi" "-oem" "-odb" "-t")
1 <- call-process-region: nil

According to the docstring, call-process-region doesn't return the exit
value, because buffer=0.
This is because mail-interactive is nil by default.

Duh!  Thank you for tracking this down.  I've changed the default of
mail-interactive with the patch below.

Just curious: Why not leave the default as-is and let-bind the variable
in emacs-report-bug?

 nil means let mailer mail back a message to report errors."
