Created an attachment (id=777)
catch functions returning CANT_INTEPRET_EXP

testcase:

class A
{
    bool delegate() dg;
    void B()
    {
        static if ( dg() )
            should error graciously;
    }
}

Produces:
ice.d(6): Error: value of 'this' is not known at compile time
Segmentation fault (core dumped)

Catching it in gdb, occurs in interpret.c at CallExp::interpret, around line
2720. A few assignments, no checking whether or not any returned
EXP_CANT_INTERPRET.

Currently rebuilding using the attached change...
