[Octave-bug-tracker] [bug #62152] Textscan fails in rare occurences

[Markus Mützel]

Follow-up Comment #2, bug #62152 (project octave):

A someone stripped down reproducer for "Spectrum_ABEC_3.txt":

Path2filename = 'Spectrum_ABEC_3.txt';
fileID     = fopen (Path2filename, 'r');
formatSpec = repmat ('%f', 1, 75);
delimiter  = ' ';
startRow   = 105;
endRow     = 144;
dataArray  = textscan (fileID, formatSpec, endRow-startRow+1, 'Delimiter',
delimiter, 'MultipleDelimsAsOne', true, 'HeaderLines', startRow-1,
'ReturnOnError', true, 'EndOfLine', '\r\n');
fclose (fileID);
assert (dataArray{24}(27), 7.45644633363295e-5)


I didn't write that here before: When I remove one of the digits of that
number in the source text file, the entire file reads correctly. That's what
makes me suspicious about the buffering that seems to be happening in
chunks...
