Compiler Warning with -Wunreachable-code

Hi,

On compiling my code with flag -Wunreachable-code, I'm getting compiler warnings
../source/XmlFile.cpp:203: warning: will never be executed

Line 203 reads
throw XmlException("XmlFile::BLAH!!!");

This exception is thrown explicitly and obviously works !!

I'm using
$ gcc --version
gcc (GCC) 4.2.1

on debian Linux
$ uname -a
Linux H00001 2.6.26-1-686 #1 SMP Sat Jan 10 18:29:31 UTC 2009 i686 GNU/Linux

Compiler bug or am I just imagining things?

Regards
Ishdeep

TITLE

       Language::INTERCAL::Bytecode - intermediate language

DESCRIPTION

       The CLC-INTERCAL compiler works by producing bytecode from the program source; this bytecode can be interpreted to execute the program
       immediately; alternatively, a backend can produce something else from the bytecode, for example C or Perl source code which can then be
       compiled to your computer's native object format.

       The compiler itself is just some more bytecode. Thus, to produce the compiler you need a compiler compiler, and to produce that you need a
       compiler compiler compiler; to produce the latter you would need a compiler compiler compiler compiler, and so on to infinity. To simplify
       the programmer's life (eh?), the compiler compiler is able to compile itself, and is therefore identical to the compiler compiler compiler
       (etcetera).

       The programmer can start the process because a pre-compiled compiler compiler, in the form of bytecode, is provided with the CLC-INTERCAL
       distribution; this compiler compiler then is able to compile all other compilers, as well as to rebuild itself if need be.

       See the online manual or the HTML documentation included with the distribution for more information about this.
