I've got a very strange problem and I wanted to ask if you guys have any 
ideas.

Yesterday I compiled my project with dmd 1.041 and Tango and it worked. 
Today I compiled the same code again to get started (I sometimes like to 
just do a full rebuild to get started) and I get this message:

/usr/local/bin/../import/tango/math/IEEE.d(641): number is not representable

The only thing that really has changed since the last build is that I 
upgraded to Karmic today. But I can't think of any connection, besides maybe 
the linking that could be affected by that. So I thought I'll ask here, 
maybe someone of you can think of anything.

Thanks,
Mike

It could be that the C library routine strtold(), which the lexer relies 
on, changed. That has nothing to do with linking.

Hmm. This is where dmd struggles:

641:    [0x1.a5f1c2eb3fe4efp+73, 0x1.A5F1C2EB3FE4EFp-1,   74],    // normal

I have no idea how the lexer works, but that sounds pretty plausible when I 
look at that constant in there.

Anyway, after further investigation I figured out that it's a unittest, so I 
just commented it out and it compiles now without problems. Maybe it's just 
a fluke, I guess we'll see if someone else will have the same problem. I, 
for one, am satisfied; my code compiles, and that is all that counts.

Some additional info: I tried it with dmd 1.050 too, same thing. My Tango 
import is a rather current checkout, I diff'd against a checkout I made 
about 15 minutes ago and the problematic file is the same as in Tango's 
trunk. And nothing compiles as soon as I import tango.math (which in turn 
imports IEEE.d).

That's odd. Please try adding an 'L' to end of each of each constant.

Oh, I'm really sorry, I copied the wrong line (this was 640). Here's the 
guilty line (641, this time for real):

     [0x1.fa01712e8f0471ap-1064,  0x1.fa01712e8f0471ap-1,     -1063],

Adding 'L' to the first constant works:

     [0x1.fa01712e8f0471ap-1064L,  0x1.fa01712e8f0471ap-1,     -1063],

Thanks!
