It is successful on GCC 13. The version of util linux this was tested on was 2.39.3. ` reduced.i: In function ‘probe_btrfs’: reduced.i:16:6: error: gimple_bb (stmt) is set to a wrong basic block 16 | void probe_btrfs() { | ^~~~~~~~~~~ # .MEM_16 = VDEF <.MEM_2> __builtin_memcpy (&state, p_9, 16); during GIMPLE pass: sccp reduced.i:16:6: internal compiler error: verify_gimple failed ` gcc -v: Using built-in specs.
