> Is it possible that those of you who have seen failures have some crap
lying around in /tmp which is interfering with your build and/or
doctesting? I'm still trying to understand why some people have problems
and others don't.
If things in /tmp are a problem, then I feel that should be considered a
bug. One should be able to write something to /tmp and some other package
not read or write the same file. (That's currently happening on t2, which
the ECL developer admits is an ECL bug. He assumed temporary file names
created by 'mktemp' can't have a dot in their name, but that is not
required by POSIX standards, and occasionally on Solaris tmp files have a
dot in their name.) But I suspect mktemp on Linux does not use a dot,
otherwise the issue would have been noticed before.
I've seen failures with sage-4.5.alpha4 which are repeatable but go away
as soon as I do an rm -r of $HOME/.sage. However, they were unrelated to
the Maxima issues.
This bug sure is weird. It might depend on what way the wind is blowing or
the longitude. Has anyone in Europe seen this bug?
If the system is low on memory, it could mean Sage mis-compiles. It would
probably be worth logging the free memory 20 seconds or so, to see if it
runs low. There are probably times of the day (i.e. longitude) where the
system gets more use and so memory is lower.
