[Bug-gsl] gsl_ran_discrete_preproc "bug"

[Srećko Jurić-Kavelj]

Hi,

I ran over a bug in gsl_ran_dicrete_preproc that manifests only on
certain computers. I've attached info and test case backtrack of two
computers where bug manifests. One of them is Versalogics Cobra
(http://www.versalogic.com/products/ds.asp?productid=164#Specs) -
Pioneer 3-DX onboard computer, and other is Toshiba Satelite Pro U300;
you can see that from the dmidecode.txt. Versalogic's Cobra runs
Debian lenny (gsl version 1.11+dfsg-1) and Toshiba Ubuntu 8.10 (gsl
version 1.11-2).

The problem is with bigs and smalls stack (randist/discrete.c).
Although the same code is used when calculating the size of stacks and
when inserting (that's when the problem manifests) in them it seems it
works differently (FPU unit?). I've solved this temporarily with
allocating stacks of fixed size (Kevents).
