[Bug] strread() elaborated format strings

[Júlio Hoffimann]

Dear all,

strread('1 2 3 4 5 6',"%*n%n%*[^\n]")

The ugly format string above should produce 2 as output, i'm trying to reproduce the AWK capability of returning the 2-th column of a text file with textread() (which uses strread() under the hood).

Explaining the format:

%*n ignore the first number

%n get the second one

%*[^\n] ignore the longest non-empty string containing characters different of EOL.

In Octave 3.7.0+ from hg, the command produces an error:

strread('1 2 3 4 5 6',"%*n%n%*[^\n]")

error: strread: A(I): index out of bounds; value 1 out of bound 0

error: called from:

error:   /opt/octave/share/octave/3.7.0+/m/io/strread.m at line 294, column 7

Someone could confirm the bug?

Regards,

Júlio.
