+Unreachable code
+Description of problem:
+There is always a false condition in the function `alloc_code_gen_buffer_splitwx_memfd` in the file `tcg/region.c`. If `buf_rw == NULL` we go to the mark __fail__:
+
+https://gitlab.com/qemu-project/qemu/-/blob/master/tcg/region.c?ref_type=heads#L580-L583
+
+But the value of `buf_rx` is __`MAP_FAILED`__:
+
+https://gitlab.com/qemu-project/qemu/-/blob/master/tcg/region.c?ref_type=heads#L577
+
+And this line will never be reached:
+
+https://gitlab.com/qemu-project/qemu/-/blob/master/tcg/region.c?ref_type=heads#L601
