Build with: perl Tools/Scripts/build-jsc --gtk --debug


The following test case triggers this assertion error:

---


Test case:
---
Object.prototype.localeMatcher = "invalid";
Intl.NumberFormat.prototype.resolvedOptions();
---

Similar issues can be reproduced with:
---
Object.prototype.localeMatcher = "invalid"; 
Intl.NumberFormat.prototype.format(0);
---

And:
---
Object.prototype.localeMatcher = "invalid"; 
Intl.Collator.prototype.resolvedOptions();
---

And:
---
Object.prototype.localeMatcher = "invalid";
Intl.Collator.prototype.compare();
---

Does no longer reproduce at r215724, because the Intl prototypes are no longer Intl object instances.
