Found it.... MessageDigest md1("Foo") uses 'createInstance(...)' in a
PIMPL. However, createInstance(...) [incorrectly] declared it throws a
"InvalidArgumentException". In reality, the function throws a
"NoSuchAlgorithmException".

Visual Studio ran fine because MSVC ignores the exception
specification (http://msdn.microsoft.com/en-us/library/wfa0edys%28v=VS.90%29.aspx).

I'm running with -Wall, -Wextra, which did not help me. Would anyone
know the warning I am looking for? I did not see it at
http://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html.
