Why do I get a DEPFUN error when compiling code that has IMPORTDATA function using MATLAB Compiler 4.18 (R2013a)?

I have MATLAB code that uses the IMPORTDATA function to read in files. When I try to deploy this code, using either MCC or DEPLOYTOOL, with any of the MATLAB Compiler or Builder products, I get the following error:

%

ERROR: Depfun error 'unexpected standard exception from mex file.
What() is
 ..'
Error using mcc
Error executing mcc, return status = 1 (0x1).

This issue occurs only on certain Linux machines, and if I have the IMPORTDATA function present in my code.

This is a bug in MATLAB Compiler 4.18 (R2013a).

To workaround this issue, use alternative functions for reading in data such as LOAD, TEXTSCAN or DLMREAD.

To get more details on the alternative methods, see:
