Commented Issue: Continuous Allocation of V8ScriptEngine Can Crash Application [106]

$

0
When allocating a V8ScriptEngine objects within a loop causes memory to remain allocated even if you force all references to the object to null and eventually crashes the application with a System.AccessViolationException. The details of the crash is below.

_Currently coding against version 5.4.5.0 of ClearScript._

__This Code Snippet Fails (Normally at iteration 134 the failure occurs)__
for (int i = 1; i <= 1000; i++)
{
var v8Engine = new Microsoft.ClearScript.V8ScriptEngine();
v8Engine = null;
}

__This Code Snippet Works:__
for (int i = 1; i <= 1000; i++)
{
var v8Engine = new Microsoft.ClearScript.V8ScriptEngine();
v8Engine = null;
//Invoking Garbage Collection Every 50 V8ScriptEngine object allocated
//Fixes the issue
if(i%50 == 0)
GC.Collect();
}

Comments: One thing I forgot to mention is that from time to time we may have to reconfigure the initialized script engines by de-allocating and reallocating them. Hence the purpose of doing these type of allocation tests.
