Bug ID: 111693 Summary: Online manual mentions -Wuse-after-free but does not document it further Product: gcc Version: 13.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c Assignee: unassigned at gcc dot gnu.org Reporter: jonathan.leffler at gmail dot com Target Milestone: --- In the 13.2.0 documentation (https://gcc.gnu.org/onlinedocs/gcc-13.2.0/gcc/Warning-Options.html), the list of options enabled by "-Wall" includes "-Wuse-after-free=2", but there is no further mention of the option on the page. Similarly, in the 12.3.0 documentation (https://gcc.gnu.org/onlinedocs/gcc-12.3.0/gcc/Warning-Options.html), the list of options enabled by "-Wall" includes "-Wuse-after-free=3", but there is no further mention of the option on the page. It is not mentioned at all in earlier manuals, presumably because it wasn't available in the earlier versions. It would be helpful to know what the values 2 and 3 mean, and presumably what 1 and 0 mean too.
