import std.stdio: File;
void main() {
    auto f = File("missing").byLine();
}



If I compile and run this program with dmd 2.061alpha with "-g" it correctly
gives a stack trace (with no line numbers):

dmd -g -run test.d

std.exception.ErrnoException at std\stdio.d(315): Cannot open file `missing' in
mode `rb' (No such file or direct
ory)

If I compile and run it without "-g" (dmd -run test.d) it doesn't show the
std.exception.ErrnoException, and the program just crashes with no error
messages at run-time.

Maybe this is a regression.
