Hi, When running the example, sometimes it showed the message. Do you have any idea?

Thanks,

Hi, Not much information to go on there. Perhaps trying running under gdb/lldb?

Hi, What is gdb/lldb? Thank you.

Hi, We can use “gdb lua” to load Lua into GDB and type “run speech.lua” to see the debugging information. However, it’s not easy to reproduce the error of “segmentation fault”. I guess it is a hardware issue, and might only happen when the machine is busy.

Starting program: /usr/bin/lua speech.lua
