I've got the following message while compiling some code:

test.d: In function `main':
test.d:4: error: unrecognizable insn:
(insn 14 12 15 0 (set (reg:XF 61)
        (const_int 0 [0x0])) -1 (nil)
    (nil))
test.d:4: internal compiler error: in extract_insn, at recog.c:2083

I got the code down to the following fragment:
void main()
{
    real temp = 3;
    temp = !temp;
}

Is this a known bug, or am I doing something wrong maybe?

Please file a bug report.
(I could reproduce this issue with GDC-0.22 but not with GDC-0.23)
