Bug ID: 110394 Summary: Lambda capture receives wrong value Product: gcc Version: 13.1.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: other Assignee: unassigned at gcc dot gnu.org Reporter: jackyguo18 at hotmail dot com Target Milestone: --- Note that this doesn't occur in Clang, and to my knowledge, disabling strict aliasing and overflow would make no difference. The code submitted here is actually part of a larger library. When I go to debug it, a lambda in `GetKeys(int index, BUTTONS* keys)` captures the wrong value for `index`--it should be 0, but it's 23. Changing the capture type from value to reference causes the lambda to inexplicably call the address 0x17 (decimal 23).
