[issue44728] Testsuite fails on x86_64

2021-07-23 Thread Erich Eckner 


New submission from Erich Eckner :

The following tests fails on x86 32 bit:

test_cmath test_math test_posix test_turtle - looks, like the expected 
precision is too high.

Full log is attached.

[issue34096] testsuite fails assertion

2018-07-11 Thread Erich Eckner 


New submission from Erich Eckner :

building python 2.7.15 on archlinux32 (the i686 branch of archlinux) from 
source succeeds, but running the testsuite (with some segfaulting tests 
disabled - see issue34095) results in an assertion error:

yes, indeed, I just tested with your three flags-variables set and the 
build+test succeeded - I'll have to figure out what the minimal change is, 
though :-)

2018-07-16 Thread Erich Eckner 


Erich Eckner  added the comment:

yes, you were absolutely right: just adding "-fwrapv" to $OPT is enough.

Ok, is this something, we at archlinux32 need to opt in for, or is this 
something, that the configure script should add for x86?

[issue34095] [2.7] test_idle fails with: /usr/bin/xvfb-run: line 181: 3617 Segmentation fault

2018-07-16 Thread Erich Eckner 


Erich Eckner  added the comment:

> Can you try to get the Python traceback and/or C traceback using gdb?
Sry, I can't - I don't know how to use gdb :-(
Is there some one-line command which makes gdb start xvfb-run and attach to it? 
Or do I need to start xvfb-run and separately attach gdb to it? (how do I do 
this?)

> ... and hence would need xvfb-run on a headless server, as opposed to a 
> workstation with screen.  Erich, I assume you are running on the latter.

I'm running this on a headless box (packaging for archlinux32). Setting up a 
desktop on the test box would be some effort, but should be possible in 
principle.

In the original PKGBUILD which Eli posted, there is a comment about when the 
tests started failing - which suggests, the problem is connected to xvfb-run.

2018-07-16 Thread Erich Eckner 


Erich Eckner  added the comment:

ah, that would explain, why we don't get it set automatically on archlinux32 - 
there's "export OPT=$CFLAGS" right infront of ./configure ... - so $OPT is set 
and thus, -fwrapv is not appended
