          Issue ID: 18653
           Summary: [REG2.080] ICE in statement.d  'global.gaggedErrors ||
                    global.errors'
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: ice-on-invalid-code
          Severity: major
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: greensunny12 at gmail.com

The following code triggers an ICE in ~master, but 2.079 triggers the error
correctly.

---
void main()
{
    import std.ascii, std.algorithm, std.stdio;
    stdin.byLine
        .map!(l => l.chunkBy!((a, b) => !(a == '_' ||
std.ascii.isAlphaNum(a)));
}
---

This doesn't seem to be the first time this assert got triggered in ICE (see
e.g. https://issues.dlang.org/show_bug.cgi?id=14621)
