With gcc-12, I get for test-case gdb.base/vla-struct-fields.exp: ... (gdb) print inner_vla_struct_object_size == sizeof(inner_vla_struct_object)^M $7 = 1^M (gdb) XPASS: gdb.base/vla-struct-fields.exp: size of inner_vla_struct_object ... Fix this by limiting the xfailing to gcc-11 and earlier. Also, limit the xfailing to the equality test. Tested on x86_64-linux.
