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.
