Segmentation fault when parse static buffer

[GoogleCodeExporter]

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 <severity>Low</severity>

 $rats -w3 --xml test.cpp 
<?xml version="1.0"?><rats_output>
<stats>

<dbcount lang="ruby">46</dbcount>

<dbcount lang="php">55</dbcount>
</stats>
<analyzed>test.cpp</analyzed>
<vulnerability>
  <severity>Low</severity>
Segmentation fault (core dumped)

What version of the product are you using? On what operating system?
RATS v2.3 on FreeBSD 10.0 amd64

If the report is exported to an xml file, this file end unexpectedly. This 
cause trouble to other tool exploiting this report.

Tested with different syntax:
static char gParseBuffer [MAX_SIZE];
char gParseBuffer [MAX_SIZE];
char g [MAX_SIZE];
char g [1];
All segfault. But this work if circle by a function:
int main() { char g[1]; }
or just
{ char g[1]; }

Declaring a global array out of any block will cause rats to segfault.
