I tried and noticed the following things: - When running Sage's tests (I do that with ". local/bin/sage-env && sage- starts && sage-maketest"), I notice that this problem seems to be randomly triggered - I tried to run failing tests manually, which then succeeded. Also, another testrun showed failures with different testcases. - This problem showed up first with Sage 4.4 (Steven reported this) and remains in 4.4.1, upgrading to python-2.6.5-r99 did not change anything (I upgraded python and ran revdep-rebuild, but I did not recompile sage-core/sage-clib). - As long as I did not try to exit Sage everything seems to be ok - I opened Sage with "sage -gdb" and typed several simple commands (2+2, maxima('2+2'), integral(sin(x),x,0,pi)) which worked fine - when I type quit there is the possibilty that Sage exits with failure. GDB (I typed "bt" for backtrace) reports now the known error: *** glibc detected *** /usr/bin/python2.6: corrupted double-linked list The backtrace does not give very much information just function calls in libc and python itself. - I removed the patch for sage-clib which replaces gmp with mpir - this did not change anything noticable. - I just found this bugreport from numpy which could trigger this problem: http://projects.scipy.org/numpy/ticket/1464 Cheers, Christopher
