[Octave-bug-tracker] [bug #63806] catch block output is displayed after text from rethrow (Matlab Compatibility)

[Rik]

Follow-up Comment #2, bug #63806 (project octave):

Interestingly, we are already trying to do the right thing here.  Try this
code which adds a call to warning().


try
  z = zeros (2^53,1);
catch ME
  disp ('in catch block');
  warning ("warning in catch block");
  rethrow (ME);
end


which results in


in catch block
warning: warning in catch block
warning: called from
    blah at line 5 column 3

error: out of memory or dimension too large for Octave's index type
error: called from
    blah at line 2 column 5


So, apparently the warning function does flush stdout before proceeding. 
Given that Octave is an exception state, performance isn't important.  It
seems like rethrow() should borrow the code that warning() uses and flush
stdout before proceeding.
