Python crashes with a floating point exception on SF's Alpha/Linux 2.2 machine in the compile farm: $ ./python Python 2.3b1+ (#2, Jun 17 2003, 10:50:58) [GCC 2.95.4 20011002 (Debian prerelease)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> pow(1e200+1j,1e200+1j) Floating point exception $ |

Logged In: YES user_id=21627 Can you tell whether you were compiling with -ieee? |

Logged In: YES user_id=89016 Doesn't seem that way: gcc -pthread -c -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -I. -I./Include -DPy_BUILD_CORE -o Objects/complexobject.o Objects/complexobject.c Changing OPT in Makefile to include -ieee and recompiling doesn't fix the problem, I still get a "Floating point exception". |

Logged In: YES user_id=21627 Ah, I see: LINUX. This is probably a compiler bug, without even looking at the details. |

Does the error occur with Python 2.6, too? |

Probably related to this. test_pow fails on alpha with both 2.4.4 and 2.5.2.
test test_pow failed -- Traceback (most recent call last):
File
"/var/tmp/portage/dev-lang/python-2.4.4-r9/work/Python-2.4.4/Lib/test/test_pow.py",
line 109, in test_bug705231
eq(pow(a, 1.23e167), 1.0)
ValueError: negative number cannot be raised to a fractional power
I'll test with 2.6 and report back.

Did you get some results? |

Closing this due to lack of feedback. Ali Polatel's report looks like an entirely separate issue; most likely an alpha libm bug. |
