So from the other e-mails the answer is that it is
a compiler optimization bug.
And for my setup (Suse 9.2, gcc version 3.3.4 (pre 3.3.5 20040809)
the same is true, i.e. only "-fno-f2c" has to be omitted
in the OPTS in the make.inc (from INSTALL/make.inc.LINUX)
for LAPACK.

Great - many thanks for all the help!

And to Nils question:

In my case it seems to be enough to do
  export LAPACK=/opt/python/lib/libflapack.a
and the corresponding one for BLAS
before compiling scipy.

Best,
