Package: gedit
Version: 2.12.1-2
Severity: normal
if the contents of a file are a long datalist that does not consist of
newlines, gedit will perform very slowly, hog a bunch of ram, then crash.
the following code (which computes the largest known prime and outputs
that number to stdout; http://fabrice.bellard.free.fr/mersenne.html)
is a demonstror of this bug. the output causes gedit to
practically grind to a halt. the problem arises because the output
contains no newlines. the computation itself only takes about 3 minutes
on my 1.6 GHz processor:
#!/bin/bash
echo '''#include stdio.h
int m=754974721,N,t[124],a,*p,i,e=30611555,j,s,c,U;f(d){for(s=124;s/=2;d=d*
1LL*d%m)if(sN)for(p=t;pt+N;p+=s)for(i=s,c=1;i;i--)a=*p+p[s],p[s]=(m+*p-p[s])*1LL
*c%m,*p++=a%m,c=c*1LL*d%m;for(j=0;iN-1;){for(s=N/2;!((j^=s)s);s/=2);if(++ij)
a=t[i],t[i]=t[j],t[j]=a;}}main(){*t=2;U=N=1;while(e/=2){N*=2;U=U*1LL*(m+1)/2%m;f
(362);for(p=t;pt+N;p++)*p=*p*1LL**p%m*U%m;f(415027540);for(a=0,p=t;pt+N;)a+=*p
(e1),*p++=a%10,a/=10;}while(!*--p);t[0]--;while(p=t)printf(%d,*p--);}'''
