I would file a bug report, but can't determine if this is in the IO 
package or elsewhere.  I've searched the __COM_spsh_open__.m, xlsopen.m, 
and xlswrite.m files and see no "feval" anywhere.  There is nothing by 
the name com_set in the main IO package files or the private subdirectory.

Philip, could you please take a look at the file

http://sourceforge.net/p/octave/code/11662/tree/trunk/octave-forge/main/io/inst/private/__COM_spsh_open__.m#l19

?  Note the comment calls this __COM_xlsopen.m__  (why are the 
underscores after the 'm' and not the 'open'?)

## __COM_xlsopen.m__ - Internal function for opening an xls(x) file 
using COM/ActiveX

but it is actually __COM_spsh_open__.m.

Where is the "actxserver" routine that gives a portal to ActiveX?

    app = actxserver ("Excel.Application");

Perhaps that is where there is an feval failing with com_set.
