D.gnu - Crash when iterating over files with foreach and std.file.dirEntries

I'm wondering if anyone has experienced a crash when using 
dirEntries to iterate over files. This is for the Windows 32 bits 
build of gdc from the gdc downloads page and it happens for both 
the 5.2.0 and 4.9.3 gcc versions (I haven't tried any others). It 
works correctly for the 64 bit builds though.

I'm wondering if this is a known issue (I couldn't find anything) 
or if I should get a minimal example going. Crash seems to happen 
when exiting a foreach loop.

I think somebody already reported this. The windows builds are
unsupported right now and there are likely many similar issues. I hope
we'll have stable MinGW builds at the end of this year.

Should I file an issue in the bugzilla just in case? And if it 
makes you feel better, this is the first issue I've encountered 
with the MinGW builds.

yes you should and please post the code you have used because I 
would be curious to reproduce it myself.

Thanks

Absolutely. I'm going to spend some time narrowing this down and 
making sure I know what exactly is causing it before I post any 
code though.

After minimizing my code, I am now wondering if it has something 
to do with ranges in general or if it is related to just 
dirEntries. This will cause a crash:

module test;

import std.stdio;
import std.file;


void main(string[] args)
{
	writeln("Testing");

	auto directoryEntries = dirEntries("C:\\", SpanMode.shallow);

	writeln("fails?");

}//crash on exiting the scope


And if we try to do something with the range we get a crash 
earlier.


module test;

import std.stdio;
import std.file;
import std.array;


void main(string[] args)
{
	writeln("Testing");

	auto directoryEntries = array(dirEntries("C:\\", 
SpanMode.shallow)); //crash here

	writeln("fails?");//never printed

}

Just to reiterate, this happens with 32 bit gdc only. The 64 bit 
gdc works correctly for this.
