Hi Mark,

Fixed very elegantly in commit 849a1399ca46497ad6acc5b11903f345502c02de.

The fact that it’s C++ makes things a little bit more complicated, and
it makes the bug a little bit more likely to trigger (because in C++ you
can have declarations of ‘static const’ things, and a declaration
doesn’t have an initializer, hence the NULL pointer dereference.)

Thanks for the heads-up,
Ludo’.
