There is no support for catching such errors, at least there is none yet.

Translating them to C++ exceptions sounds like translating SIGABRT or 
other errors to C++ exceptions to me, in a similar fashion to what 
Visual C++ does with SEH; i.e. not a good idea.

On a technical note, it might be a bit complicated to do, since that 
state is global so it could be hard in the presence of threads.

We'll nevertheless look into the details of this.
