Hello again!
The crash appens here :
void Execution::ProcessDebugMessages(bool debug_command_only) {
Isolate* isolate = Isolate::Current();
// Clear the debug command request flag.
isolate->stack_guard()->Continue(DEBUGCOMMAND); // << KABOOOOOOM !!
StackLimitCheck check(isolate);
if (check.HasOverflowed()) {
return;
}
Any idea of what's happening ? :(
Regards,
Florent STEINER
