Probably the internal buffer is too small.

You can increase the buffer? Or make it a dynamically changing

Please help

I stuck that in a test topic, built it, did :verify on that topic in windows and Linux with no problem. So I can’t see the problem yet. Can you rebuild your Linux with -g e.g. from chatscript main do:  g++ -lpthread -lrt -funsigned-char src/*.cpp -g
and run gdb a.out
and set args local
and run
then do it and crash. Then do backtrace   and send me the results?
