Hi,

My code:

#include <v8.h>
#include <v8-debug.h>
#include <iostream>
#include <string>
#include <assert.h>

using namespace std;
using namespace v8;

static Local<Value> execJsScript(const std::string& jsCode) {
Local<String> source = String::NewFromUtf8(Isolate::GetCurrent(), 
jsCode.c_str());
Local<v8::Script> script = Script::Compile(source);
assert(!script.IsEmpty());
return script->Run();
}

void test_js_DebugBreak() {
cout << "V8 version: " << v8::V8::GetVersion() << endl;

auto isolate = Isolate::New();
Isolate::Scope isolateScope(isolate);
HandleScope handleScope(isolate);
Handle<Context> context = Context::New(isolate);
Context::Scope contextScope(context);
auto globalObj = context->Global();

v8::Debug::EnableAgent("test", 5858, true);
v8::Debug::DebugBreak(isolate);

// I get this error here:
// # Fatal error in ..\..\src\compiler.cc, line 274
// # CHECK(feedback_vector_->length() == length) failed
execJsScript(
"function foo(f) { f(); };"
"function enqueueMicrotask(callback) {"
" foo(wrapped);"
" function wrapped() {"
" callback();"
" }"
"};"
"enqueueMicrotask(function() {"
" throw new Error('fooerr');"
"});"
);
}


Am I doing something wrong? Or is this a bug in V8? This is V8 3.25.8.

Thanks,
Albert
