VM aborts when calling IGuest::getProcessOutput with non infinite timeout — 於 初始版本

描述

Context: I'm using Python bindings to vboxapi.

Everything's fine when calling IGuest::getProcessOutput with an infinite timeout (0).

The problem is that calling IGuest::getProcessOutput with a non infinite timeout (1000 ms, 10000 ms, etc.) causes the VM to abort.

Extract from VBox.log:
