With CONFIG_DEBUG_COREDUMP_MEMORY_DUMP_LINKER_RAM, buffer_output() is called on the entire RAM memory area. This includes the stack for the coredump thread, which is where tmp_buf is stored. Eventually, it will copy (parts of) tmp_buf into tmp_buf itself, which invokes Undefined Behaviour in memcpy(): > The memory areas must not overlap. Use memmove(3) if the memory areas do > overlap. - memcpy(3) With picolibc, this is detected in __memcpy_chk() and causes a fault in __chk_fail().
