New issue 1741 by [email protected]: C++ use TryCatch in nested throws
an unexpected exception.
http://code.google.com/p/v8/issues/detail?id=1741
For Code
#include <v8.h>
#include <stdio.h>
using namespace v8;
Handle<Value> foo(const Arguments &args)
{
// another trycatch
TryCatch trycatch;
puts(*String::Utf8Value(args[0]));
return v8::True();
}
int main()
{
puts(V8::GetVersion());
HandleScope scope;
Handle<Context> context = Context::New();
Context::Scope context_scope(context);
context->Global()->Set(String::New("foo"),
FunctionTemplate::New(foo)->GetFunction());
TryCatch trycatch;
Handle<Value> result = Script::New(String::New("foo('hello')"),
String::New("core"))->Run();
if (trycatch.HasCaught()) {
puts(*String::Utf8Value(trycatch.Message()->Get()));
}
return 0;
}
----
It will output
3.6.5 (candidate)
hello
Uncaught undefined
----
the trycatch in main HasCaught() returns true. it not always happen, run 10
times about 8 times will show 'Uncaught undefined'. The script works right
in 3.2.10.2
