Comment:

 I tried to compile the program on my laptop

 {{{
 manzyuk at paddy:~/tmp$ uname -a
 Linux paddy 2.6.32-35-generic #78-Ubuntu SMP Tue Oct 11 16:11:24 UTC 2011
 x86_64 GNU/Linux
 }}}

 and it runs without visible problems.  Of course, it is unacceptably slow,
 but it doesn't crash.  My laptop runs GHC 7.0.3, and the only difference
 I've noticed so far compared to my desktop is `gcc`:

 {{{

 Can I provide any other useful information about my desktop?  Or maybe you
 have suggestions how I can try to debug the program?

 Frankly, to my shame, I didn't know it was a horrible way to compute
 primes until yesterday.  I've been taught this wrong implementation of the
 sieve of Eratosthenes, but have never actually tried it before.  I am
 pleased to have re-discovered a queue-based algorithm today.

 I should fix the broken packages, thanks for pointing this out.
