Hi, the following code calls ‘trace_context()’ which is created only later on line 254. This is triggered if the first arg of ‘context()’ is of type ‘table’. ······ ············································ function test (str) context.starttext() context(str) context.stoptext() return 0 end t = {"a", "b"} return test(t) ····· ············································ Moving l. 254 to around l. 114 in mult-cld.lua fixes it for me.
