Hello,
Why could V8 be crashing trying to run a script containing errors? Below is
how I run the compilation and the script itself
*// const char* src comes as argument *
*v8::Isolate* isolate = v8::Isolate::GetCurrent();*
*v8::HandleScope hScope(isolate);*
*v8::Local<v8::Context> context = context_.Get(isolate);*
*v8::Context::Scope ctxScope(context);*
*v8::Local<v8::String> source = v8::String::NewFromUtf8(isolate, src);*
*v8::Local<v8::Script> script =
v8::Script::Compile(isolate->GetCurrentContext(), source).ToLocalChecked();*
*v8::TryCatch trycatch(isolate);*
*v8::Local<v8::Value> v =
script->Run(isolate->GetCurrentContext()).ToLocalChecked();*
*if (v.IsEmpty()) {*
* v8::Local<v8::Value> exception = trycatch.Exception();*
* v8::String::Utf8Value exceptionStr(isolate, exception);*
*}*
Javascript:
*log("first line");*
*log("second line");*
*var a = 2;*
*var b = 5;*
*var c = a + b;*
*log("" + c); // My C++ callback assumes arguments is String :-) *
*var d = new Something(); // crash here*
I've also tried with these start-up options:
*--stack-size=4096 --abort_on_uncaught_exception=false --hard-abort=false*
This is the crash code:

The backtrace's last two entries are my function which calls the script
execution followed by v8::base::Abort()
If I remove the last line from the javascript, everything works fine.
