2.10.2 bessel_I(1,1,"scipy") bug

[Kate]

When I build 2.10.2 from source on my
x86-Linux box (pentium4-fc6) using gcc-4.2.3,
I get a 'make check' failure at

./sage -t devel/sage-main/sage/functions/special.py

sh: line 1: 3345 Illegal instruction /home/kate/sage/sage-2.10.2-
x86-Linux/local/bin/python .doctest_special.py >.doctest/out
2>.doctest/err

A mysterious error (perphaps a memory error?) occurred, which may have
crashed doctest.
[3.6 s]
exit code: 256

The offending line seems to be

sage: bessel_I(1,1,"scipy")
/home/kate/sage/sage-2.10.2-x86-Linux/local/bin/sage-sage: line 212:
3484 Illegal instruction sage-ipython -c "$SAGE_STARTUP_COMMAND;"
"$@"

Hi Kate,

this is now #2303. I will check out if I can reproduce this anywhere
and we will hopefully have a fix soon. It is a blocker for 2.10.3.

Cheers,

Michael

Sadly, this bug still appears in 2.10.3.

Kate,

Unfortunately I don't have a single machine where I can replicate this problem:

sage: bessel_I(1,1,"scipy")
[boom].

So it will have to wait until we have access to such hardware. Does anybody
out there have a computing where the above doesn't work that I can use?
