@anchao hi, I suspect you might not have CONFIG_SCHED_HAVE_PARENT or CONFIG_CANCELLATION_POINTS enabled. Configuration that needs to be opened: ``` CONFIG_SCHED_HAVE_PARENT=y CONFIG_CANCELLATION_POINTS=y ``` test on sim: build: `tools/configure.sh sim:nsh; make -j16` result: <img width="1308" height="367" alt="Image" src="https://github.com/user-attachments/assets/fad6d06a-d79b-4cfd-86e4-1f9f9212f2c5"; /> test on qemu-armv7a: build: `tools/configure.sh qemu-armv7a:nsh; make -j16` result: <img width="1307" height="364" alt="Image" src="https://github.com/user-attachments/assets/7d73bc74-91f2-412f-a8b2-75a1b0de8e35"; /> The crash mentioned above was caused by the execution flow described below. ``` thread_parent ---------------------------------thread_child detach() group_leave() nxsig_cleanup() free()---->block! ---------------------------------------------------group_leave() ---------------------------------------------------check no member in group, release thread_parent. ---------------------------------------------------exit() release_tcb()--->double free!!! ``` -- This is an automated message from the Apache Git Service.
