Subject: dl-load.c (ld.so) bug??
Date: Mon, 21 Jun 1999 17:52:13 -0500 (CDT) [thread overview]
Message-ID: <Pine.LNX.4.04.9906211749280.27642-100000@narn.local.drgw.net> (raw)
testcase:
#include <stdio.h>
int main(void){
char * ptr;
printf("hello world\n");
fflush(stdout);
ptr = (char *)malloc(100);
free(ptr);
}
compile this with:
gcc test.c -lefence -g -static
On a PPC glibc-2.1 box, this segfaults in dl-load.c:564
On a x86 Red Hat 6.0 system, it works fine (
[troybenj@mos6 troybenj]$ ./a.out
Electric Fence 2.0.5 Copyright (C) 1987-1998 Bruce Perens.
hello world
[troybenj@mos6 troybenj]$
Either dl-load.c has a serious bug, or ElectricFence is broken on PPC.
I suspect it's the former, and if so, this would explain the weird
segfaults I've been seeing.
Can someone that knows glibc better please confirm or deny this for me?
