Hi Qian,
you are a hero. THANK YOU!!!
I've now increased the number of processors of the VM to 4 and the
compilation succeeded.
That doesn't, of course, deal with the actual bug, but as you suggested,
the best we can do is to report that problem to the sbcl developers.
===============
Cannot save core with multiple threads running.
Interactive thread (of current session):
#<THREAD "main thread" RUNNING {10004F84C3}>
Other thread:
#<THREAD "finalizer" RUNNING {1001640053}>
===============
I wonder at which point these two threads are created. I cannot imagine
that FriCAS code is doing it, because I don't see "thread" in the code.
