Could people reporting this problem please include their compiler and
binutils versions (gcc -v ; ld -v).  I am running 2.4.19-xfs from
immediately after it was released, and I cannot reproduce the problem.
Tested on UP and SMP using
  Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
  gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-81)
  GNU ld version 2.10.91 (with BFD 2.10.91.0.2)
