Thanks, I am carefully reading it!
By the way, I got something very strange here.
`find_recursive_construction` is a cached function (with the decorator in
`sage.misc.cachefunc`). It appears that after some of the interruption,
the `CachedFunction` class suddenly decided that the function now takes 3
arguments instead of 2... and trying to call it with 3 values instead of 2
I just got an unhandled SIGSEGV.
Might be something subtle going on with exception and cache but I do not
know why. I can describe the case in more details.
