Summary: [14] ICE: in extract_bit_field_1, at expmed.cc:1838
Product: gcc
Version: 14.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rtl-optimization
Assignee: unassigned at gcc dot gnu.org

We found that a case caused ICE on Ubuntu 22.04.3 LTS.
We used spack to install gcc-14.2.0, so we are not very sure if crash is caused
by gcc.
Compiler flags: -O3 -flto -march=native -fno-omit-frame-pointer
