[PATCH] Overload test failure patch

[ahaas@neosoft.com]

Hi.

I believe one test in the 'overload' tests fails because of
a potential problem in the test program, not gdb. The failure
I see is when gdb prints out the values of instance 'foo_instance1'
of class 'Foo'. This instance is called with the constructor
function taking an integer as a parameter. The character pointer
parameter 'ccpfoo' is never initialized to anything, so when
gdb executes 'print foo_instance1' it prints out

{ifoo = '111', ccpfoo = 0xXXXXXX "{stuff}"}

instead of

{ifoo = '111', ccpfoo = 0x0}

as the test expects.

My patch modifies the constructor function to explicitly set
the pointer to null in this case, thus making the test pass.

I'm not a C++ programmer by a long shot, so this
patch may be compensating for an issue regarding the compiler -
egcs-1.1.2, i586 - but I really, really doubt that.

Use the patch as you see fit.
