Details:

I use evalc() to attempt to extract the version number of GLPK, using the
following line of code ...


str = evalc('glpk(1, 1, 1, 1, 1, ''U'', ''C'', -1, struct(''msglev'', 3))');


However, it prints the following to the console ...


GLPK Simplex Optimizer, v4.60
1 row, 1 column, 1 non-zero
Preprocessing...
~     0: obj =   1.000000000e+00  infeas =  0.000e+00
OPTIMAL SOLUTION FOUND BY LP PREPROCESSOR


... while capturing only the following ...


octave:2> str
str = ans =  1


Identical behavior observed on 4.2.0 on Windows 7 in running in a VM and on
4.2.0-rc4 on macOS Sierra 10.12.1 using a MacPorts build of octave-devel
(octave-devel
@4.2.0-rc4_0+accelerate+app+docs+fltk+gfortran+graphicsmagick+qt5+sound).
