The OSCI simulator catches (most of) the exceptions, that are thrown
from within your model. It tries to make some sense out of it, but only
a few types are statically checked.

Your code throws an exception, which is not caught inside your model.
Which one? Frome where? Well, you have to find out.
Do you have a debugger on your platform (e.g. GDB)? You can try to
"break on exceptions". In GDB, this could be done with the command
'catch throw'. You could also try to break on the function '__cxa_throw'.
The the execution stops immediately, when the exception is thrown, and
you can look at the backtrace in the debugger to find the origin in your
code.
You don't have a debugger?
Well, get one. ;-)
Greetings from Oldenburg,
