Bug ID: 107020
Summary: [OpenMP][UBSAN] ICE during GIMPLE pass: sanopt via
ubsan_expand_vptr_ifn: "output_operand: invalid
expression as operand"
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code, openmp
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
CC: jakub at gcc dot gnu.org
Target Milestone: ---
Created attachment 53620

Reduced testcase, compile as: g++ -fopenmp -fsanitize=undefined test.ii
That's with https://github.com/SOLLVE/sollve_vv and running:
g++ -fopenmp -fsanitize=undefined -I ompvv \
tests/5.0/application_kernels/declare_target_base_and_derived_class.cpp
tburnus@dem-tobiasb-u20:~/repos/sollve_vv-upstream> g++-commit -fopenmp
-fsanitize=undefined -I ompvv
tests/5.0/application_kernels/declare_target_base_and_derived_class.cpp
during GIMPLE pass: sanopt
tests/5.0/application_kernels/declare_target_base_and_derived_class.cpp: In
function ‘main._omp_fn.2’:
tests/5.0/application_kernels/declare_target_base_and_derived_class.cpp:70:3:
