Details:

in current dev (works fine in 4.0)

Save this as textscantest.m:


FID = fopen('textscantest.m', 'r');
f = textscan(FID, '%s', 'delimiter', '\n');
fclose(FID);
f


and execute! Result:


>> textscantest

f =
{
  [1,1] =
  {
    [1,1] = FID = fope
    [2,1] = ('textsca
    [3,1] = test.m', 'r');
    [4,1] = f = textsca
    [5,1] = (FID, '%s', 'delimiter', '
    [6,1] =
    [7,1] = ');
    [8,1] = fclose(FID);
    [9,1] = f
  }
}
>>


This looks like a wrong interpretion of '\n'

But there must be more bugs, when reading long textfiles some binary garbage
is appearing in the output...
