module bug;

void blah(int[char] as)
{
    //auto k = as;
    auto k = [6: as];
}

$ dmd -v -m64 -c bug.d

The first auto line, if enabled, compiles just fine.  The second doesn't.

Program received signal SIGSEGV, Segmentation fault.

When fixed, the block in dmd's compilable/interpret3.d that's versioned out to
just run on x86/32 should be changed to run on all platforms.  See also this
