I don't know. The problem is that the crt unit now uses the dpmiexcp unit
(to be able to have ctrl-c as input instead of having it abort the
program).

The dpmiexcp installs default signal handlers for most signals, so they
are then caught by the dpmiexcp unit instead of by the system unit. Since
the sysutils unit simply converts runtime errors (which also can be
exceptions caught by the system unit and then converted into a runtime
error) into exceptions, it won't work anymore.

We can solve this by not hooking any exceptions anymore by default in the
dpmiexcp unit, but I don't know if that's a good solution.
