(original) (raw)

test_math is currently failing on the Debian/alpha buildbots (trunk and py3k).

I've been trying, unsuccessfully, to figure out what's going wrong, and I'm

starting to run out of ideas, so I thought I'd ask the list for help to see if

anyone has any useful suggestions.

Details of the failure:  running the following code:

from math import log

ar = 9.88e-324

x = log(ar)

produces:

ValueError: math domain error

Somehow, it looks like errno is getting set to something nonzero in

math\_1\_from\_whatever in mathmodule.c, but I really can't figure out

how.

I've tried adding '-mieee' to the gcc compile flags, and I've added a bunch

of autoconf tests to verify that log(9.88e-324) succeeds, produces

roughly the right result, and doesn't set errno to anything nonzero.  

All the autoconf tests that should pass do.  So I can't find anything

wrong with the libm implementation of log.

test\_math is fine on Tru64/alpha.

Does anyone have access to a Linux/alpha machine, and a few minutes

to figure out exactly what's failing?  Or any suggestions about what might

be failing.  I'm open to wild ideas at this point... :-)
