Version: 0.8.1-2
Severity: normal
debci scipy tests fail on i386 when testing against blis.
The failing test is test_arpack.py::test_hermitian_modes, which
triggers a segfault:
linalg/eigen/arpack/tests/test_arpack.py::test_symmetric_modes PASSED [ 1%]
linalg/eigen/arpack/tests/test_arpack.py::test_hermitian_modes Fatal Python
error: Segmentation fault

line 879 in arpack.py refers to unpacking with complex numbers:
else:
# complex is so much simpler...
d, z, ierr =\
self._arpack_extract(return_eigenvectors,
howmny, sselect, self.sigma, workev,
self.bmat, self.which, k, self.tol, self.resid,
self.v, self.iparam, self.ipntr,
self.workd, self.workl, self.rwork, ierr)
Are there any known problems using blis with complex numbers?
The same test passes with openblas and atlas.
The latest failing test log is 2022-01-17 13:11:36 UTC
https://ci.debian.net/data/autopkgtest/unstable/i386/s/scipy/18402204/log.gz
After this, I'll disable this test in scipy/blis so that i386 can
register clean tests.
