### Description
Hello,
I am compiling NuttX for an STM32H753ZI and I have issues with getting `ps`
to work.
Relevant options in my `.config` (full config bottom of message):
```
CONFIG_FS_PROCFS=y
CONFIG_FS_PROCFS_REGISTER=y
CONFIG_NSH_PROC_MOUNTPOINT="/proc"
```
Compiled with CMake and the `nucleo-h743zi:nsh` target.
I then flash with openocd and open picocom on /dev/ttyACM0 to get an nsh
prompt.
First thing weird, proc is not mounted? Should it be mounted automatically
by stm32_bringup.c here:
```c
#ifdef CONFIG_FS_PROCFS
/* Mount the procfs file system */
ret = nx_mount(NULL, STM32_PROCFS_MOUNTPOINT, "procfs", 0, NULL);
if (ret < 0)
{
syslog(LOG_ERR,
"ERROR: Failed to mount the PROC filesystem: %d\n", ret);
}
#endif /* CONFIG_FS_PROCFS */
```
So I mount it manually with `mount -t procfs /proc` and then run:
```shell
nsh> usleep 10000000 &
sh [2:100]
nsh> ps

Why did it crash the second time?
I tried changing `CONFIG_TASK_NAME_SIZE` with no success.
I tried increasing `CONFIG_SYSTEM_NSH_STACKSIZE` to 4096 as mentioned in
#11463 with no avail, only change was reported stack size in the crash:
```

```
Any help greatly appreciated.
