modp_dtoa returns crap pointer in corner cases

[GoogleCodeExporter]

Ahhh I see.
I should store a null in the output.

Right now the function doesn't return a char*.  I can't change that without 
breaking ABI compatibility (I think).


Let me make a test case and fix will be forthcoming.


thank you!

Actually, I misread my own code.   The function does not return a pointer, it's 
void, so if you are using the return value, it's likely to be bogus.

 The corner cases do 'return' but also set the buffer to 'nan' or 'inf' as appropriate.

In general i think these function SHOULD return a pointer, but i can't change 
it now without breaking binary compatibility.


Thanks for your time here.  If you think I got this wrong, please reopen.
