> Issue Type: Bug
> Components: DRLVM
> Environment: Windows and Linux
> Reporter: Vera Petrashkova
> Priority: Minor

> The following synthetic test demonstrates that debug VM crashes when it tries to start thread.
> It is occurred on jitrino in default, jet and opt modes.
> But test passes on interpreter.
> It also passes on release VM.
