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

OPTIONS

       -h, --help
	      Display help text and exit.

       -o DIRECTORY, --outputdir DIRECTORY
	      Output directory.

       -O LEVEL
	      Compiler optimization level.

       -c CACHE, --cache CACHE
	      Use JIT compiler cache.

       -i METHOD, --integration-method METHOD
	      Specify integration method. METHOD may be either quadrature (default) or symbolic.

       -d ORDER, --integration-order ORDER
	      Specify integration order.

       -w, --dolfin-wrappers
	      Generate DOLFIN C++ wrapper code.

       -b, --benchmark
	      Run benchmark of element tensor computation.

       -s, --safemode
	      Use safe mode when generating (quadrature) code, writing complete integrand expressions unmodified.
