Please test pari-2.7.2 prerelease 2 |
Dear PARI developers, I have made a second prerelease of PARI 2.7.2 to address the following serious issues 27- FpXY_evaly() wrong when evaluating at 0 [F56] 28- [mingw] gp could crash at start up [#1607] [F57] Source: <http://pari.math.u-bordeaux.fr/pub/pari/snapshots/pari-2.7.2-pre2.tar.gz> Windows installer: <http://pari.math.u-bordeaux.fr/pub/pari/windows/snapshots/Pari-2-7-2-pre2.exe> basic windows binary: <http://pari.math.u-bordeaux.fr/pub/pari/windows/snapshots/gp-readline-2-7-2-pre2.exe> The expected release date is still set to the 19/09/2014 Below is the changelog: Done for version 2.7.2 (released 19/09/2014): [last column crossreferences current development release 2.8.0] Fixed 1- gaffsg(0, t_PADIC): wrong valuation [F21] 2- (t_INTMOD with word-sized modulus)^(huge negative power) [#1584] [F24] 3- (gp -p N) or (primelimit=N in gprc_ for N >= 436273290 resulted in an incorrect primetable. N.B. Such commands are now useless: needed primes are produced dynamically anyway. [F25] 4- monomial(exact zero, d, v) returned an invalid t_POL / t_RFRAC [F26] 5- contfracpnqn(v, n) returned partial quotients p[-1]/q[-1] ... p[n-1]/q[n-1], instead of the documented p[0]/q[0] ... p[n]/q[n] [F27] 6- factor((3+4*I)/25) -> factor 2+I had 0 exponent [#1586] [F29] BA 7- iferr() could crash if some component of the t_ERROR were clones. [F31] 8- nffactor() could overflow the stack when default accuracy too low [F32] BA 9- obsolete use of E=[a1,a2,a3,a4,a6] in ellmul crashed [#1589] [F33] 10- incorrect rounding in mulrr/divrr for one-word precision reals [F34] BA 11- multiif did not handle correctly return() in conditions [#1590] [F35] 12- [0..5] -> [0,0,0,0,0] on some architectures [F36] 13- is_gener_Fp could return wrong results [F37] 14- Fq_sqrtn(t_INT,..,&zeta) could return a wrong root of 1 [F38] 15- bnfinit: SEGV due to precision issues [#1592] [F39] 16- zm_zc_mul only worked for square zm matrices [F40] 17- genus2red(0,27*x^5+97*x^4+118*x^3+60*x^2+13*x+1,3) -> bug [#1596] [F41] 18- [ghelp] oo loop when $COLUMNS too small [#1594] [F42] 19- genus2red(x,-x^6-3*x^4-10*x^2-1,3) -> impossible inverse [#1597] [F43] 20- factoru(1) returned a t_MAT instead of the expected "matsmall" [F44] 21- FpM_charpoly wrong in small characteristic [#1602] [F45] 22- when compatible = 3; series() used a random precision [F50] 23- genus2red(0,6*x^6+5*x^4+x^2+1,7) -> impossible inverse [#1597] [F51] 24- isprime() could crash on large input [#1604] [F52] 25- genus2red(x^3+1,1) -> type error [#1597] [F53] 26- gphelp did not handle === correctly [#1603] [F54] 27- FpXY_evaly() wrong when evaluating at 0 [F56] 28- [mingw] gp could crash at start up [#1607] [F57] Thanks in advance for testing, Bill.
