Bug report for Octave 2.1.73 configured for i686-pc-cygwin
Description:
-----------
* The error message above is printed and then Octave aborts the following
script file:
=======================================================================
nTimes = 2;
nChans = 1;
center_frequency = 1;
x = ones(nTimes, 2*nChans);
if center_frequency > 0
sig = zeros( nTimes, nChans );
for chan = 1:nChans
sig(:,chan) = complex( x(:,2*chan-1), x(:,2*chan) );
end
else
sig = x;
end
========================================================================
problem. Suggestions or general comments are also welcome.
Repeat-By:
---------
* Step 1: save the file above as junk.m.
* Step 2: run octave in same directory.
* Step 3: execute the command "junk".
* Result: assertion "nread == 1" failed: file "lex.l", line 1998
Fix:
---
* If possible, replace this item with a description of how to
fix the problem (if you don't have a fix for the problem, don't
