Hi, I got segfault recently and still can't figure out why. #0 0x0000000000467c67 in lj_str_new () #1 0x000000000047a802 in lj_cf_ffi_string () #2 0x000000000047d64e in lj_BC_FUNCC () #3 0x000000000046ba00 in lua_pcall () Trying to reproduce this case, could someone give me some clues/hints? Thanks. Cheyi
