When are /tmp files cleared?

When are /tmp files cleared?

[marxin]

Ups, false alarm

Sorry!

That happens :)

[marxin]

Thank you for the report. I can confirm I used to have issues with temporary files, but that ought to be fixed.
Can you please share the content of ./creduce_probe.sh file?

> find /tmp -maxdepth 1 -type d -name "cvise-*" | wc -l
61

This one is fishy, that should not happen. This one is weird:

1.9M	/tmp/ice-000530.cpp
8.0K	/tmp/ice-000530.sh

Because cvise operates only inside the created /tmp/cvise-* subfolders.

@marehr And cat you please test the pushed commit? It should help us investigating what leaves the /tmp/cvise* folders.

My ./creduce_probe.sh files looks like this:

I'm currently right within a reduction, I'll try out the patch once it is done.

Oh, I just noticed that the ice-XXXXX.sh files are artefacts generated by clang and not cvise

Sorry!

Now I need to find out how to disable clang's auto-generated bug-reproducer files xD
