AFIR, you need to compile without debug as debug initializes the variables.

And you need to use Windows. The above mentioned changeset seems indeed to be responsible, as the initialization of the variable has been taken out.

The problem was introduced by the fix of bug#57232, and already fixed in all trees, starting from 5.5.
