Hi, I am running the latest minimals on a 64bit Linux system and ran into a luatex crash with a specific file. I reduced the file down to a simpler version that still triggers the crash, and thought it would be of some interest to post (the resulting pdf, if generated, will be ugly since I removed a lot of formatting, and some of the code in the file may appear extraneous). I am running: $ context --version mtx-context | ConTeXt Process Management 0.60 mtx-context | current version: 2012.09.06 23:03 $ luatex --version This is LuaTeX, Version beta-0.70.2-2012052410 (TeX Live 2012) What I think makes this interesting is the same file does not crash on three other setups I tested: - 32bit OS X (beta-0.70.2-2012052310) - 64bit OS X (beta-0.70.2-2012052309) - the same Linux system, but I replaced the 64bit Linux luatex binary with the 32bit Linux binary (beta-0.70.1-2012052416 (rev 4277), I see this is an older version but I downloaded directly from the minimals site today). It rebuilt caches and processed the file successfully. I updated minimals on both OS X systems today so all three systems should be otherwise identically configured. Various alterations to the file can avoid the crash; a few I found are---adding a \strut before the word jumbo, removing the nested bTABLE (this appears to be unneeded in the attached example), removing the \definefontfeature statement at the top of the file. Anyway I'd be interested to know if anyone else sees the same issue. I'm sure this is a real edge case error but hope it is helpful to track down the problem. Please let me know if there is any other debugging info you would like to see from my end. Thanks, Brian
