Segmentation fault when parse static buffer

```
What steps will reproduce the problem?
1. write "static char gParseBuffer [MAX_SIZE];" in a file test.cpp
2. run rats -w3 --xml test.cpp

What is the expected output? What do you see instead?
Expected to see the xml report of the Low warning: "fixed size global buffer".
Got a segmentation fault just after Low

$rats -w3 --xml test.cpp

If the report is exported to an xml file, this file end unexpectedly. This
