open a range of files - segfault

[Stephan Schiffels]

Hi,

this code crashes with a segfault. I need help to understand what 
might be wrong with it.


import std.array;
import std.algorithm;

void main() {
  auto names = [file1.txt, file2.txt, file3.txt];  // let 
these files exist

  auto files = names.map!(f = File(f, r))().array();
}

Thanks,

Stephan

If I use the latest 2.063beta5 compiler, and I also import 
std.stdio, then I see no crash on Windows32.

A quick gdb run shows that it's segfaulting at the exit of the 
program, when the GC runs its final full collection.

With git master on linux x64 I get a segfault, see my other
comment.

OK, thanks for confirming. I updated to the latest git master and 
still get a segfault. I'll file a bug report.
