In C mode, compiling a code with a non-closed function body besides an ordinary error produces Internal error: func 281 (was func 279 in previous versions of dmc), thus preventing the compiler from seeing the rest of the code. The function must have some arguments to make this happen.

void f(int n)
/* Neither void f(void) nor compiling this as
** C++ code produces Internal error: func 281. */
{

void g(void)
{
a bunch of code with possible errors follows
}
