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@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.
