Something seems to be wrong with the powerpc copy relocations.
Attached is a binary for testing (qemu-ppc works fine). It is compiled
from
#include <stdio.h>
extern char **environ;
int main(int argc, char **argv)
{
printf("%p %p\n", environ, &argv[argc + 1]);
return 0;
}
Output before dynamic linker overhaul:
0xf6f4f830 0xf6f4f830
and after:
0 0xf6f4f830
It seems to me that the dynamic linker indeed copies environ, which is
0 at that point, but that __init_libc uses the old location of environ.
