Posix_GCC demo: stack smashing detected

Kernel
1

Hello everyone,

I am new in FreeRTOS and I am trying to execute de Posix_GCC on Ubuntu 22.04.4 LTS.

I am using gcc 11.4.0 and make 4.3

When I launch the ./posix_demo I got this

[WARN] pthread_attr_setstack failed with return value: 22. Default stack will be used.
[WARN] Increase the stack size to PTHREAD_STACK_MIN.

Trace started.
The trace will be dumped to disk if a call to configASSERT() fails.
Starting full demo
*** stack smashing detected ***: terminated

Any suggestion is really appreciated.

Thank you in advance.

Which version are you using? I tried the mainline and I do not see this crash. Here is my command history:

gh repo clone git@github.com:FreeRTOS/FreeRTOS.git
cd FreeRTOS/
git submodule update --init --recursive 
cd FreeRTOS/Demo/Posix_GCC/
make
./build/posix_demo

And here is the output I see -

Trace started.
The trace will be dumped to disk if a call to configASSERT() fails.
Starting full demo
OK: No errors - tick count 10001 
OK: No errors - tick count 20001

make and gcc versions are also same as yours:

Hi,

I downloaded the code from the web site, not from GIT.

I have been requested for other project for some days.

When I get round to test it, I will let you know the result

Thank you for your answer
Jose

It works.

What is on the website and what is on GitHub is not the same.
