std.conv.parse!int uses a counter just to see if anything could be parsed. When the counter overflows, the state jumps back to "at start", which is wrong, of course.

Test case (takes some minutes):
---
import std.conv: parse;
import std.range: chain, repeat;
void main() {
    auto seven = chain(repeat(cast(dchar) '0', size_t.max), "7");
    assert(parse!int(seven) == 7);

    auto eleven = chain(repeat(cast(dchar) '0', size_t.max), "B");
    assert(parse!int(eleven, 13) == 11);
}

Pull request follows.
