I have a nightly build that builds a source tree with several compilers/options. I'm using buildbot on centos 6, though I doubt that buildbot has any relation to the problem.
Sometimes the build fails with a bunch of messages like:
Assembler messages:
Error: can't open /tmp/ccqjY5HV.s for reading: No such file or directory
My first guess is that something is deleting these files behind the compiler's back. I've looked at the tmpwatch cron job but the setup doesn't seem like a culprit.
The failures seem to happen around 10pm when several builds launch. The actual compiles are locked so that only one compile happens at a time.
Any thoughts welcome.
