           Summary: [Home]
           Product: D

Following code raises assertion failure (buffer.data() returns empty string).
With the marked line it passes. It seems like formattedWrite is unable to write
to empty appender.

import std.array;
import std.format;

int main() {
    Appender!string buffer;
    // buffer.put(""); // with this line it passes
    formattedWrite(buffer, "foo");
    assert("foo" == buffer.data());
    return 0;
}
