Package: lua-5.1 Version: 5.1.5-7.1 Severity: normal Dear Maintainer,
A multithreaded server where each thread uses its own lua state to run lua code crashes during socket IO/http calls via lua-socket version 3.0~rc1-3. Crashes do not occur if I use my own lua compilation with -pthread flag. There seems to be some discussion about this topic in the internet, for example: https://lwn.net/Articles/654762/ . Therefore I request that lua would be built with the -pthread flag in upcoming package versions. Several other well known scripting languages such as Python, Perl and Ruby are compiled with -pthread to allow safe multithreading.
