Comment(by jdemeyer):
The last patch fixes the tanh() issue, it was caused by RR(0.0)._pari_()
creating an invalid GEN (it took me a very long time to figure this out).
I added a debug() function to gen objects calling dbgGEN() from the pari
library, example:
{{{
sage: pari('[1/2, 1.0*I]').debug() # random addresses
[&=0000000004c5f010] VEC(lg=3):2200000000000003 0000000004c5eff8
0000000004c5efb0
1st component = [&=0000000004c5eff8] FRAC(lg=3):0800000000000003
0000000004c5efe0 0000000004c5efc8
num = [&=0000000004c5efe0] INT(lg=3):0200000000000003
(+,lgefint=3):4000000000000003 0000000000000001
den = [&=0000000004c5efc8] INT(lg=3):0200000000000003
(+,lgefint=3):4000000000000003 0000000000000002
2nd component = [&=0000000004c5efb0] COMPLEX(lg=3):0c00000000000003
00007fae8a2eb840 0000000004c5ef90
real = gen_0
imag = [&=0000000004c5ef90] REAL(lg=4):0400000000000004
(+,expo=0):6000000000000000 8000000000000000 0000000000000000
}}}
Apart from that, a lot of cleanups, and some more doctests.
As far as I can tell, everything works now on my system, apart from some
doctest failures in elliptic_curves (again, I do not plan to look at
this).
