Issue #83, Regression because of "Support for comparison of C strings (char *) added.":
A test program will crash if one of the pointer is not valid.
For example:
char *foo = 0;
TS_ASSERT_EQUALS(foo,(char *)0);
Since the commit 4b8f9430fd8d3f3de725dbf52468dc56ded115b3 , this two lines
will now produce a SIGSEGV signal.
=> added a test to check if at least one of the pointers is NULL,
if yes, check if their values (their address not the content pointed to) are equals.
