- Subject: octave3.2: strchr triggers Octave:str-to-num
- From: Kim Hansen <kim@i9.dk>
- Date: Wed, 10 Nov 2010 17:38:50 +0100

Package: octave3.2
Version: 3.2.4-8
Severity: normal
Tags: patch
strchr treats a string as a number implicitly:
kim@raph:~/orion/svn/raph1/octave$ octave
GNU Octave, version 3.2.4
....
octave:1> warning error Octave:str-to-num
octave:2> strchr("Octave is the best software","best")
error: implicit conversion from string to real N-d array
error: type conversion failed for binary operator `+'
error: evaluating argument list element number 1
error: invalid empty index list
error: called from:
error: /usr/share/octave/3.2.4/m/strings/strchr.m at line 37, column 16
octave:2>
I think it can be fixed by changing the the strchr function to:
function varargout = strchr (str, chars, varargin)
if (nargin < 2 || ! ischar (str) || ! ischar (chars))
print_usage ();
endif
f = false (1, 256);
f(uint8(chars) + 1) = true;
varargout = cell (1, nargout);
varargout{1} = [];
[varargout{:}] = find (reshape (f(uint8(str) + 1), size (str)), varargin{:});
endfunction
I found this bug by doing this:
warning error Octave:str-to-num
oldpath = path;
path(oldpath);
If the octave-octcdf package is installed this will fail.
Regards,
Kim Hansen

Closes: 603046
Changes:
octave3.2 (3.2.4-10) unstable; urgency=low
.
* New patches
- fixes-for-gcc-4.6: GCC 4.6 no longer includes the headers that defined
size_t automatically; and it doesn't like 'inline' in explicit
instantiations either (closes: #603046). The latter bug isn't mentioned in
the bug report, but was seen once the first bug was fixed. Thanks to Orion
Poplawski from Fedora for the original patch.
- avoid-implicit-conversion: explicitly convert strings to numbers
(closes: 603046). Thanks to Kim Hansen for the patch.
