Bug ID: 98937
Summary: [11 Regression] pointer_query cache leaks
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: rguenth at gcc dot gnu.org
Target Milestone: ---
==25237== 2,634,236 bytes in 1 blocks are possibly lost in loss record 9,732 of

(tree-ssa-strlen.c:5602)
==25237== by 0x13366A4: dom_walker::walk(basic_block_def*) (domwalk.c:309)

==25237== by 0x9E6112: execute_pass_list_1(opt_pass*) (passes.c:2657)
looks like there's no DTOR for pointer_query::cache_type so strlen_dom_walker
will not release the two vectors.
