Description H.J. Lu 2004-09-29 16:24:30 UTC 
When NPTL libraries are used, I get a linker assertion
failure. To reproduce on Fedora 2:

[hjl@gnu errno]$ cat bug.c
extern int errno;
 
int
main ()
{
  printf("errno=%d",errno);
  return 0;
}
[hjl@gnu errno]$ gcc bug.c -L/usr/lib/nptl
collect2: ld terminated with signal 11 [Segmentation fault]
/usr/local/bin/ld: BFD 2.15.92.0.2 20040927 assertion fail
/export/linux/src/binutils/binutils/bfd/elflink.c:6123
Comment 1 H.J. Lu 2004-09-29 16:41:15 UTC 
The problem is there is no-TLS access to TLS symbol.
