Hello,
I recently built Sage on my laptop running Ubuntu 17.10 (x86 - 64 bit). It
worked perfectly, and successfully ran all of the basic tests (I never ran
the long tests). I tried to start it up today and it wouldn't work, because
it said it could not find the directory that I had set as SAGE_ROOT (I
don't remember exactly what it was set as, I think maybe /usr/bin/sage or
something like that), and indeed this directory no longer existed. I tried
to rebuild Sage in order to fix the issue, and it hasn't worked since
Every time I try to start Sage, it crashes immediately. I get this error
that seems to be coming from Pari somewhere but the error messages are
baffling to me. I've tried rebuilding multiple times and nothing helps. I
guess what I'm trying to say is that I KNOW that it's possible for Sage to
work on my machine, as I had already done it. I just can't figure out what
got broken or how to fix it. Any help would be much appreciated.
Thanks,
Dillon Ethier
