Bug ID: 107476
Summary: Spurious stringop-overflow warning
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: pkoning at gcc dot gnu.org
Target Milestone: ---
Created attachment 53803

Reproducer. Compile with -O3
The attached code produces a stringop-overflow warning complaining that the
code is writing into offset 1 of a one entry array (ttix_buf, reference in
ttix_svc). In fact it does not, since the index is the control variable in a
for loop that ends on a < one check.
Curiously, if I increase the size of the ttix_buf array, I still see the error
at size 2 or 3, but no complaints at size 4 or above.
