I found the issue by going through the code. 
Essentially, it is the following:

str = [];
sprintf("%s", str);

Now, with respect to 'my' code - this is not really my code. I am looking
at matlab2tikz and the code in question is executed as part of the acid
test shipped with it. The file is publically available at
https://raw.github.com/nschloe/matlab2tikz/master/src/matlab2tikz.m

The issue happens in the function drawPatch().
