            Bug ID: 98457
           Summary: [d] writef!"%s" doesn't work with MonoTime / SysTick
           Product: gcc
           Version: 10.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: d
          Assignee: ibuclaw at gdcproject dot org
          Reporter: witold.baryluk+gcc at gmail dot com
  Target Milestone: ---

void main() {
  import std.stdio;
  import core.time : MonoTime;
  writef!"%s"(MonoTime.currTime());
}


Doesn't compile with gdc 10.2.1:

(null):0: confused by earlier errors, bailing out



Adding manually .toString() makes it work (at the expense of possible extra
allocation).

No issues in ldc2 1.24.0 or dmd2 2.095.0-beta.1

It doesn't look like issue in phobos, but something deeper.
