make check fails when optimizing with gcc-2.96-88

[David Necas (Yeti)]

Hello,

I have troubles compiling gsl-0.9 with RH's
gcc-2.96-88.  When I compile it with CFLAGS=,
`make check' passes, however, CFLAGS=-O makes a
test to fail and CFLAGS=-O2 makes whole hundreds
of tests to fail.

The important parts of `make check' outputs are
attached (CHECK-O.log and CHECK-O2.log), they
include commands used for compilation at their
start.

It may be another gcc-2.96 bug, too (in this case
you will be probably able to create a much more
useful gcc bug report than me).

I don't know what details about my system may help
you, so just basic info:

  OS: i386 Red Hat Linux 7.1 (more-or-less)
  CPU: AMD Athlon(tm) Processor stepping 02 @900MHz
  Kernel: vanilla 2.4.7 (just with i2c-2.6.0 patch)
  Compiler: gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-88)

but it should be recreatable on vanilla i386 RH 7.1
