Re: [isabelle] Isabelle2013-2-RC1 available for testing
I can confirm this.
when proving False via
proof (intro TrueE)
the system gets lost somehow (on MacOS X 10.9):
- changing the method of (intro TrueE) does not stop the system from evaluation
(comsuming 100% of CPF and eating > 4 GB of RAM)
- also if one reloads the buffer, everything remains red and evaluation continues
- sometimes even when quitting Isabelle via Cmd-Q, afterwards a poly-process remains which eats up > 4 GB RAM.
Here are some more details:
2 x 2.8 Ghz Quad-Core Intel Xeon
6 GB RAM

This also left me with a runaway process under OS X which I had to terminate manually after exiting Isabelle/Jedit.
