Buffer overflow using textscan happens in windows but not in mac

Hi there,

I'm using textscan to import a big JSON file with the following line:

MyString = textscan(fid, '%s','Headerlines',0,'Delimiter','!','CollectOutput',1,'EndOfLine','\n','BufSize',50*1024*1024);

As you see, I use textscan to read the file in a single string, because I need to parse it. The file has 43 MB.

Setting the BufSize to 50 MB will make the import work in windows 7. But under Mac, setting the BufSize to 2 MB is enough and the program will work.

Why are there such differences between mac and win? thanks

This is a question for the technical support, because the source codes of textscan are not public.
