import std.range, std.algorithm;

void main() {
    auto arr1 = [1, 2, 3, 4, 5];
    float[] f = [1, 2, 3, 4, 5];
    auto ind = sort!((int a, int b) {
        return f[a] > f[b];
    })([1, 2, 3, 4, 5]);

    auto result = indexed(arr1, ind);
}

$ dmd -inline test.d
/cis/home/dsimcha/dmd2/linux/bin64/../../src/phobos/std/range.d(5962): Error:

I can only reproduce this on Linux, only with -inline and only with the call to sort(), which isn't related in any obvious way.  I can't reproduce it with GDC, meaning it's likely a backend bug.  Therefore, my guess is that this bug is somehow related to Linux exception handling.

Created an attachment (id=1040)
DustMite'd testcase

FWIW here's a DustMite reduced testcase that gives one of the errors.

test.d(26): Error: function
test.Indexed!(void[],SortedRange!(void[],__dgliteral1)).Indexed.opSlice cannot
get frame pointer to main

What a fantastically convoluted example :-(

It shrinks down to this. Compile with -inline:

struct Foo(T)
{
        Foo opSlice(size_t a, size_t b)
        {
            return Foo(_indices[a..b]);
        }

    T _indices;
}

struct SortedRange(alias pred)
{
    SortedRange opSlice(size_t a, size_t b)
    {
        return SortedRange();
    }
}

void main() {
    auto ind = SortedRange!({ })();
    auto a = Foo!(typeof(ind))();
}

It happens on Windows, too, and is not a backend bug.
