Bug 110243 – [V8] ToNumber conversions in toIntXX() functions need try-catch block

• Status: RESOLVED
• Resolution: WONTFIX
• Component: New Bugs

[Joshua Bell]

CodeGeneratorV8.pm relies on e.g. toInt32 for coercing arguments to WebIDL long types in JSValueToNative. toInt32 calls value->ToNumber(), which may throw but in general this call is not wrapped in a v8::tryCatch block.

e.g.:

someObj.someLongMethod( { valueOf: function() { throw "boom"; } } );
