No, your test would probably not have survived longer with FX only.

We have indeed found a bug in the FXCM API, but are not sure if this was the reason of the crashes that you experienced. Do you still have the problem that it crashes as soon as you start? And is this on a private PC or a VPS? In the latter case, could you give us temporary access to that VPS with a Teamviewer session? Testing Sundance's system with Teamviever has been very helpful for finding the problem.
