BUG/MEDIUM: lua: segfault if a converter or a sample doesn't return anything In the case of a Lua sample-fetch or converter doesn't return any value, an acces outside the Lua stack can be performed. This patch check the stack size before converting the top value to a HAProxy internal sample. A workaround consist to check that a value value is always returned with sample fetches and converters. This patch should be backported in the version 1.6 and 1.7
