Package: python-scipy Version: 0.16.1-1 Severity: important On MIPS, scipy stops with an illegal instruction when running the build time tests for python-astropy , causing an FTBFS there [1]. I could trace this down to the "cephes_igam" function. The Bug is reproducible by issuing the gammaincinv function:
$ python Python 2.7.11 (default, Jan 11 2016, 21:04:40) [GCC 5.3.1 20160101] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from scipy.special import gammaincinv >>> gammaincinv(2,0.5) Illegal instruction (core dumped) Looking into the core dump, I got Program terminated with signal SIGILL, Illegal instruction. #0 0x7424ffd4 in cephes_igam () from /usr/lib/python2.7/dist-packages/scipy/special/_ufuncs.mips-linux-gnu.so (gdb) where #0 0x7424ffd4 in cephes_igam () from /usr/lib/python2.7/dist-packages/scipy/special/_ufuncs.mips-linux-gnu.so Backtrace stopped: previous frame identical to this frame (corrupt stack?)
