           Summary: [CTFE] ICE on cross-module call of function checking
                    CTFE-ability of function with invalid switch statement
           Product: D
           Version: D2
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody at puremagic.com
        ReportedBy: timon.gehr at gmx.ch

Tested with DMD 2.053.
Took me some time to reduce this:

A.d:
import B;
void main(){foo();}

B.d
int bar(){switch(0){};} // any switch statement that does not compile will do.
auto foo(){static if(__traits(compiles,{enum x=bar();})){}}


This code provokes an internal compiler error:
$ dmd A B
dmd: statement.c:2758: virtual Statement* SwitchStatement::semantic(Scope*):
Assertion `!cases' failed.
Aborted
