Error while generating code using Matlab Coder for ode45.

I am trying to generate C code using Matlab Coder for my function which uses ode45. I am getting the following error.

??? Undefined function or variable 'chunk'. The first assignment to a local variable determines its class.
Error in ==> ode2345 Line: 454 Column: 38
Code generation failed: View Error Report
Error using codegen (line 146)

How to resolve the error? Thanks a lot in advance!

Hmmm, there is no obvious way that could happen in the code when I look at it in R2017b. On the other hand, the line number that uses chunk is 451 rather than 454, which suggests that you might be using a different release?

For my future reference, ode2345 is toolbox/eml/lib/matlab/funfun/private/ode2345.m

Hi, I am using MATLAB 2015a.
