Sébastien Sablé <sa...@users.sourceforge.net> added the comment: No problem; I tried with a different compiler this time (gcc instead of xlc) and with -O0 just to be sure it is not a compiler issue. I had the same error.
I tried your test and you are right, the problem happens with log1p dropping the sign: >>> import math, cmath [52601 refs] >>> math.log1p(-0.0) 0.0 I also tried test_math but it seems to work fine: > ./python -E ./Lib/test/test_math.py testAcos (__main__.MathTests) ... ok testAcosh (__main__.MathTests) ... ok testAsin (__main__.MathTests) ... ok testAsinh (__main__.MathTests) ... ok testAtan (__main__.MathTests) ... ok testAtan2 (__main__.MathTests) ... ok testAtanh (__main__.MathTests) ... ok testCeil (__main__.MathTests) ... ok testConstants (__main__.MathTests) ... ok testCopysign (__main__.MathTests) ... ok testCos (__main__.MathTests) ... ok testCosh (__main__.MathTests) ... ok testDegrees (__main__.MathTests) ... ok testExp (__main__.MathTests) ... ok testFabs (__main__.MathTests) ... ok testFactorial (__main__.MathTests) ... ok testFloor (__main__.MathTests) ... ok testFmod (__main__.MathTests) ... ok testFrexp (__main__.MathTests) ... ok testFsum (__main__.MathTests) ... ok testHypot (__main__.MathTests) ... ok testIsfinite (__main__.MathTests) ... ok testIsinf (__main__.MathTests) ... ok testIsnan (__main__.MathTests) ... ok testLdexp (__main__.MathTests) ... ok testLog (__main__.MathTests) ... ok testLog10 (__main__.MathTests) ... ok testLog1p (__main__.MathTests) ... ok testModf (__main__.MathTests) ... ok testPow (__main__.MathTests) ... ok testRadians (__main__.MathTests) ... ok testSin (__main__.MathTests) ... ok testSinh (__main__.MathTests) ... ok testSqrt (__main__.MathTests) ... ok testTan (__main__.MathTests) ... ok testTanh (__main__.MathTests) ... ok test_exceptions (__main__.MathTests) ... ok test_mtestfile (__main__.MathTests) ... ok test_testfile (__main__.MathTests) ... ok test_trunc (__main__.MathTests) ... ok ./Lib/test/ieee754.txt Doctest: ieee754.txt ... ok ---------------------------------------------------------------------- Ran 41 tests in 10.467s OK ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue9920> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
