[Bug middle-end/32096] New: ICE (segfault) in vrp_evaluate_conditional_warnv


Compiling semi_empirical_int_ana.f90 of CP2k (cf. PR 29975) gives an ICE:
(with 4.3.0 20070526 on x86_64-unknown-linux-gnu)

gfortran -c -O3 -ftree-vectorize -ffast-math -march=opteron
semi_empirical_int_ana.f90
semi_empirical_int_ana.f90: In function 'dterep_ana':
semi_empirical_int_ana.f90:2321: internal compiler error: Segmentation fault

Valgrind shows:
