When a 'pragma(msg, ...)' pragma has a missing comma, the subsequent pragma(msg, ...) will result in a segfault.

------
template A(B) {
    pragma(msg, B)    // <-- missing ';'
    enum A = 0;
}
enum a = A!int;

pragma(msg, 0);
------

The error exists at least since 2.042 http://ideone.com/MVgnG, and still persists in 2.052. The segfault is raised in 'ExpInitializer::semantic' in 'init.c':


Initializer *ExpInitializer::semantic(Scope *sc, Type *t)
{
    //printf("....
    exp = exp->semantic(sc);
    exp = resolveProperties(sc, exp);
    exp = exp->optimize(WANTvalue | WANTinterpret);
    Type *tb = t->toBasetype();                        // <-- this line
