Details:

The following function, contained in the Octave file error_test.m, has an
error in line 9 (trying to compare element-wise two character arrays of
different length) which is detected by Octave during execution:


function error_test(boolflag = false)
  do
    if boolflag
      printf("true\n");   # Line 4
    else
      printf("false\n");  # Line 6
    endif
  until "abc" == "de"     # Line 9
endfunction


However, the line number given in the error message is wrong:


octave:1> error_test(false)
false
error: error_test: mx_el_eq: nonconformant arguments (op1 is 1x3, op2 is 1x2)
error: called from:
error:   /cygdrive/c/Users/tannhauser/Documents/error_test.m at line 6, column
7
octave:1> error_test(true)
true
error: error_test: mx_el_eq: nonconformant arguments (op1 is 1x3, op2 is 1x2)
error: called from:
error:   /cygdrive/c/Users/tannhauser/Documents/error_test.m at line 4, column
7


This makes it difficult to identify and to fix this kind of error, in
particular if functions are larger.
