[isabelle-dev] Fwd: [Isabelle-ci] Build failure in Isabelle

I've heard of negative thermal expansion in some materials, but I don't
think RAM is subject to it. (scnr)
In a more serious fashion: I don't see how ambient temperature could
affect memory usage. I've run into "insufficient memory" and stack
overflow problems in Isabelle several times lately, usually sporadically
Perhaps the times when 32 Bit Isabelle was enough for all applications
are indeed over.
