            Bug ID: 97330
           Summary: ice for stmt with wrong VUSE
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

Created attachment 49328
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=49328&action=edit
C source code

Sometime between 20201007 and 20201008, the attached code
has broken.

$ /home/dcb/gcc/results/bin/gcc -c -O2 -w /home/dcb/gcc/foundBugs/bug647.c 
auprocess.c: In function ‘rcm_1’:
auprocess.c:1275:17: error: stmt with wrong VUSE
# VUSE <.MEM_34(D)>
n_39 = el_35(D)->nextSample;
expected .MEM_33
during GIMPLE pass: sink
auprocess.c:1275:17: internal compiler error: verify_ssa failed
0xf02e86 verify_ssa(bool, bool)
        ../../trunk.git/gcc/tree-ssa.c:1208
0xbcd9c1 execute_function_todo(function*, void*)
        ../../trunk.git/gcc/passes.c:1999
0xbcc211 execute_todo(unsigned int)
        ../../trunk.git/gcc/passes.c:2046

I'll have a go at reducing the code.
