When I enter the words “Date of transaction” program crashes.
Error message - “Segmentation fault (core dumped)”.

OS Linux. Chatscript local mode

Interesting. Nothing happens badly on my internal copy.
Can you compile (from ChatScript top level) g++ -lpthread -lrt -funsigned-char src/*.cpp -g
and then run it as:
gdb ./a.out
set args local
run
then make it crash and do backtrace and email me that?

Program received signal SIGSEGV, Segmentation fault.
0x000000000041d817 in AssignRoles(bool&) ()

Is “Date of transaction” the literal input you typed in?  I don’t crash doing that. The trace of AssignRoles is too broad, which is why I need a stacktrace telling me which line of code did it (-g and gdb run)

crashes on mac also:

HARRY:  Did you run away from home when you were little?
diivious: > Date of transaction

that’s what I needed. thanks. Will post a new release later today.

CS 3.51 now released which should fix mac issues

In Linux (64 bit) compiling with the-g flag the error does not occur

Improvements have helped in version 3.51. thank you
