Re: [isabelle] Isabelle2014-RC0 segfault / sledgehammer raises exception DUP
Hi Fabian, Christian,

Thanks for your reports. I will look more closely into them in the coming days. I actually ran into the second issue last Friday when demoing Sledgehammer to Daniel Matichuk but could not reproduce it afterward. I also experience the first issue once in a while, sometimes with Sledgehammer, sometimes without; it seems to be related to multithreading.
I will disable MaSh for now -- it is the likely source of both problems, and I would rather play safe with the coming release. It's a pity, since the tool really does help Sledgehammer, but I don't want to see reports like this one about Isabelle2014 final if it can be avoided.
