Hi all,
I installed numpy and scipy via svn on
CentOS release 5.2
I have used the prebuild blas and lapack libraries (see 
below).

scipy.test('1','10') segfaults in

test_complex_dotc (test_blas.TestFBLAS1Simple) ...
Program received signal SIGSEGV, Segmentation fault.
0x00002aaab719a257 in cdotc_ () from 
/usr/lib64/libblas.so.3

build/src.linux-x86_64-2.4/build/src.linux-x86_64-2.4/scipy/linalg/fblasmodule.c:5310


Is this a known issue ?

Any pointer would be appreciated.

Cheers,
              Nils
