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
