> @xiaoxiang781216 I just noticed something similar when trying to create a kernel thread off of a call in `sim_bringup()` (I'm add usbhost support via libusb). I get a segfault because in `sched_dupfiles` `rtcb->group` is 0 which means parent and child are both invalid This is probably running on the IDLE thread which has no parent and the PID for the IDLE thread always zero. Zero does not mean invalid anywhere except in the case of the parent PID here. The meaning PID of zero is overloaded elsewhere too: In several POSIX APIs, PID == 0 means "this task." But that is not an issue here. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
