Bug 7845 – ICE(cgcs.c) 354

Code: ---------- import std.stdio; void main() { with(File("Vocabulary-4.txt", "rt")) foreach(s; byLine) writeln(s); } ---------- DMD64 D Compiler v2.058 on 64-bit Linux output: ---------- Internal error: ../ztc/cgcs.c 354 ---------- === Additional information === The same error for: ---------- ... auto f = File("Vocabulary-4.txt", "rt"); with(f) foreach(s; byLine) writeln(s); ... ---------- No error for: ---------- ... auto f = File("Vocabulary-4.txt", "rt"); foreach(s; f.byLine) writeln(s); ... ---------- On the following code it works well: ---------- import std.stdio; void main() { struct Foo {string s;} with(Foo("fffuuu")) foreach(c; s) writeln(c); } ----------

This works correctly on 2.059 WinXP 32.

The original issue (internal compiler error) is fixed. All problems concerning "with" statement and "File" structure will go to another issue.
