Bug ID: 112924
Summary: [14 regression] ICE when building util-linux (error:
gimple_bb (stmt) is set to a wrong basic block)
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: csfore at posteo dot net

This originally failed to compile with LTO, but I've reduced it to the
following arguments: `gcc -m32 -O2 reduced.i`. 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

Using built-in specs.
