I have always been pleased to see improvements in compile time code
execution possibilities, but today I hit what must be the weirdest DMD
error message I've ever seen:
/usr/local/bin/../include/d2/std/format.d(434): Error: can only
Applications Desktop Documents Downloads Library Movies Music Pictures
Public Sites test.d a pointer, not a 'int'
To be honest, I have no idea how this happens, but somehow DMD picked up
the contents of the directory the source file, test.d, resides in. It
looks like this (note the missing ampersand):
———
import std.stdio;
void main() {
int e;
readf( "%d", e );
}
———
Any idea what on earth could be going on here?

This is a major bug because it impacts privacy. Please file to bugzilla. Andrei

This seems way more likely than something in DMD going wild, and that's precisely the reason I asked here first before opening a bug report. The idea that it could have something to do with compile-time code execution only came to my mind because I stumbled over this while trying to trace down a CTFE-related issue anyway… I'll investigate what's expanding the star and open a bug if this really has something to do with DMD against all odds.
