// The "this" variable proxy was reused. If context annotations differ between
// uses, this can cause a use in a value context to assume a test context. Since
// it has no true/false labels set, it causes a null-pointer dereference and
// segmentation fault.

// Code should not crash:

// Original bug report by Robert Swiecki (wrapped to not throw):
try {
 new IsPrimitive(load())?this.join():String('
').charCodeAt((!this>Math));
} catch (e) {}

// Shorter examples:

this + !this;

this + (this ? 1 : 2);
