Details:

MXE-Octave 3.8.2 running on Windows 7 - About dialog tells me it is configured
for "i686-w64-mingw32"

Working on a function script and made an accidental cut-n-paste that turned a
statement that should have read 

  if currentChannelData.isNumericData 
    data            =  str2double(dataStr);
  endif

to

  if currentChannelData.isNumericData 
    data            =  str2double(dataStr);
  endevents

that provokes octave to crash when attempting to run, or even place a
breakpoint, in the script.

Windows crash handler provides the following:

Turning Diary on within octave provided the following:
