v8 version: 9.6
Hi I was able to reproduce a crash in the example shell and d8 with
following script. Before this could be caught by an OOM handler. Also if I
set the heap size to be very small (e.g. 2MB) the oom handler could still
work.
let a = [];
for (;;) a.push("test")
#
# Fatal error in
Thanks Jakob
I have realised this. I am now trying integrate chromium headless to my c
application.
Thanks

The crash means you called .ToLocalChecked() on an empty MaybeLocal. If you
run a Debug build, you should get line numbers, so you can find out where
in your source code that is.

Dear All
I am trying run a javascript available at

So that was the culprit which caused the crash. Now I ensure only the
owning thread resets the weak handles.
A question remains: why does a weak handle have to be reset? Isn't the
idea of being weak so that it can be forgotten and cleaned up as part of
garbage collections? I get memory corru

No, it's not; almost nothing in V8 is. Create a v8::Locker instance
first to ensur
have you run it with address sanitizer turned on?

My question is if one thread is calling PersistentBase::Reset() on a weak
handle while another thread is running garbage collection, is it possible
to cause memory corruption?

Ben,
Can PersistentBase::Reset() be called from a different thread from which
the isolate is attached to? Is PersistentBase::Reset() thread-safe?

Ben,
I'm not using object groups, just having weak handles in several isolates.
Calling LowMemoryNotification to force deep GC avoids the crash.
I haven't tried with latest v8 release.
Maybe I keep a count of the weak handles in my code.
