Description of problem:
In order to compile SciPy (preferably from SVN, but even the old released 
0.3.2 package), d1mach.f needs to be compiled correctly. However, the gfortran 
compiler shipped with gcc-4.0.1-4 does not compile it correctly. This is a 
known gcc bug (18518) fixed in gcc-4_0-branch. Other issues (such as incorrect 
code generation with -msse2) which ease compilation are also fixed in the 
branch above.  
The version of gcc in rawhide (4.0.2-6) fixes all these issues and is 
perfectly suitable for building SciPy. However, it requires versions of 
binutils, libtool, and glibc that are not available for FC4. Could we have a 
port of the rawhide version to FC4? 
In order to make 4.0.2-6 work with the current glibc (2.3.5-10.3) and binutils 
(2.15.94.0.2.2-2.1) on i386, I used the source rpm from Rawhide to build my 
own package with everything but the weakref patch. My understanding is that 
the updated binutils is required only on PPC, and weakref support is the only 
patch that requires the updated glibc. With the binaries built from 4.0.2-6 
without the weakref patch, SciPy compiles fine and passes all but one (corner 
case) test. However, the new gcc binary fails during compilation of ATLAS. I 
believe this may be because I need to update binutils (not an option at this 
time). Hence, the easiest route is to obtain at least an SRPM of 4.0.2-6 that 
can be used with FC4. Others have requested this on the lists as well:

Version-Release number of selected component (if applicable):
gcc-4.0.1-4

How reproducible:
Always

Steps to Reproduce:
1. Obtain SVN code from www.scipy.org (scipy and scipy_core) 
2. Compile and install 
3. python -c "import scipy; scipy.test(10,10)" 
   

Actual Results:  Segmentation fault in check_dot. 

Expected Results:  All tests should pass. 

Additional info:

To obtain and build scipy, please see the following URLs:

Then run: 
python setup.py config_fc --fcompiler=gnu95 build 
on the two repositories checked out.
