Hi, on another debian sarge based 32Bit machine (where I made a couple of links so that ATLAS is found) I get the following check_default_beta_y (scipy.linalg.fblas.test_fblas.test_cgemv) ... zsh: 8527 floating point exception The shortest example to reproduce this is gdb file /usr/bin/python run from scipy import * from scipy.basic.random import normal a = normal(0.,1.,(3,3)) x = arange(shape(a)[0]) print a print x linalg.fblas.cgemv(1,a,x) Giving
print a [[-0.70685647 0.65494695 0.9179007 ] [-0.30862233 0.58137533 2.01614468] [ 0.18585164 -0.8134587 1.23613689]] print x [0 1 2] linalg.fblas.cgemv(1,a,x)
Program received signal SIGFPE, Arithmetic exception. [Switching to Thread 16384 (LWP 26791)] 0x404167a0 in ATL_cgemvC_a1_x1_bXi0_y1 () from /usr/lib/sse2/libatlas.so.3 Does anyone else see this? Any ideas what to do with this?
