Summary: std.conv.parse faulty for floating point with -O -m32
Product: D

The following assert fails when compiled with dmd's command line options -O
-m32:
import std.conv;
void main()
{
char[] input = "1.5e3".dup;
assert(1500 == parse!double(input)); // <-- FAILS
}
It fails for float and real as well.
Please note that this combination works: -O -m64

Under platform, please put x86 if it's a 32-bit bug, even if you ran the code
on a 64-bit machine.
I can also reproduce this on Windows. Note that the answer is correct if
-release is also enabled.

This one was introduced in DMD 2.048 -> it's a regression. Also, since
optimization settings affect the result, I think it's safe to call this a
wrong-code bug.
