Why does MATLAB crash when I display a cell array containing a 1-by-128 character array?

Why does MATLAB crash when I display a cell array containing a 1-by-128 character array?

Running the following script under these circumstances produces a segmentation violation on some systems.

1. Use Linux 2.4.7-10smp #1 SMP

2. Start MATLAB 6.5 (R13) with the -nodesktop and -nosplash options in an xterm window wider than 137 characters.

3. Execute the command "FORMAT LONG"

4. Run the following script, which creates a 1-by-128 cell array. It should generate a segmentation violation at the last line.

clear

a{1}=char(32*ones(1,128));

disp('a{1}=')

a{1}

disp('a=')

a

This bug has been fixed for Release 14 (R14). For previous releases, please read below for any possible workarounds:

This is a bug in MATLAB 6.5 (R13) in the way that it displays cell arrays. Our development staff is investigating this issue.

Currently, you can try one of the following to work around this issue:

1. Run MATLAB using 'FORMAT SHORT'.

2. Run MATLAB without using the '-nodesktop' command line parameter.

3. Run MATLAB with the xterm window narrower than 137 characters.
