Hello Simon,
I have built sandbox_defconfig using origin/master (b9b83a86f0e8 ("Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sh")) on Ubuntu 23.10.
Running ./u-boot -T leads to a crash:
#9 0x00007ffff7a28189 in __libc_start_main_impl (main=0x555555591540 <main>, argc=2, argv=0x7fffffffd918, init=<optimized out>, fini=<optimized out>, rtld_fini=<optimized out>, stack_end=0x7fffffffd908) at ../csu/libc-start.c:360 360 in ../csu/libc-start.c (gdb) #8 0x00007ffff7a280d0 in __libc_start_call_main (main=main@entry=0x555555591540 <main>, argc=argc@entry=2, argv=argv@entry=0x7fffffffd918) at ../sysdeps/nptl/libc_start_call_main.h:58 58 ../sysdeps/nptl/libc_start_call_main.h: No such file or directory.

env_get("stdin") returns NULL here and should not be used without checking.
Best regards
