The following code crashes the compiler, a typo in my code contained a syntax error.

// compile with dmc -c -mn
// begin snippet
#define FOOMAC(a, b) \
{ \
    if (a) \
    { \
        foo(b); \
    } \
}

void bar(int a)
{
    FOOMAC(a == 0), 0); // this line is bad syntax, crashes compiler
}
// end snippet
