It missed 2 Mersenne Primes 9689 & 21701.
Is it my program bug or bigint broken?

Yay for first time compiling dmd :)
Sorry you had to do that!
Had to learn that once anyway :)
Maybe I'll even be able to take a stab at fixing bugs someday..

It's in a switch statement somewhere.
It sounds as though this is a bug which involves multiple files, so
it'll be difficult to reduce it.
If you're able to compile DMD, change this line in statement.c

Can you post the entire source code?
It's important that it be reprod

It's important that it be reproducible. It doesn't need to be minimal -
someone else can reduce it.

Ok, i've done some more investigating and it appears that in DMD2 a float NaN is
0x7FE0 (in dword format) but when it initialises a float 'out' parameter it
initialises it with 0x7FA0H. This causes an FPU trap which is where the time
is going. This looks like a bug to me. Can

This program:

Not really important, because I'm currently interested in cast only.
Thank you.
That is odd, I would think that i+i generates the

Hi,
This program, compiled with dmd 1.065 under Linux, crashes:

It looks like d is not initialized before opAssign() is called.
It doesn't cr

No, because then it fails for ulong.
It's those bloody C implicit conversions.

The only working sigature for array-of-structs-comparison to work is

But this removes the ability to compare against ints.

It probably has the same root cause as bug 4066.
