Hi Sage-on-Gentoo-amd64 users, |
2 |
|
3 |
yesterday I have tested the recent version of Sage to check if the problem |
4 |
Steven first reported remain - which unfortunately is the case. I tried and |
5 |
noticed the following things: |
6 |
|
7 |
- When running Sage's tests (I do that with ". local/bin/sage-env && sage- |
8 |
starts && sage-maketest"), I notice that this problem seems to be randomly |
9 |
triggered - I tried to run failing tests manually, which then succeeded. Also, |
10 |
another testrun showed failures with different testcases. |
11 |
- This problem showed up first with Sage 4.4 (Steven reported this) and remains |
12 |
in 4.4.1, upgrading to python-2.6.5-r99 did not change anything (I upgraded |
13 |
python and ran revdep-rebuild, but I did not recompile sage-core/sage-clib). |
14 |
- As long as I did not try to exit Sage everything seems to be ok - I opened |
15 |
Sage with "sage -gdb" and typed several simple commands (2+2, maxima('2+2'), |
16 |
integral(sin(x),x,0,pi)) which worked fine - when I type quit there is the |
17 |
possibilty that Sage exits with failure. GDB (I typed "bt" for backtrace) |
18 |
reports now the known error: |
19 |
|
20 |
*** glibc detected *** /usr/bin/python2.6: corrupted double-linked list |
21 |
|
22 |
The backtrace does not give very much information just function calls in libc |
23 |
and python itself. |
24 |
- I removed the patch for sage-clib which replaces gmp with mpir - this did |
25 |
not change anything noticable. |
26 |
- I just found this bugreport from numpy which could trigger this problem: |
