--- Comment #11 from eggert at cs dot ucla.edu --- Created attachment 49783 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=49783&action=edit another instance of a -Wreturn-local-addr false alarm I ran into a different instance of the bug today, while working on another Gnulib source file lib/canonicalize.c. A stripped-down test case attached. To reproduce the problem: $ gcc -O2 -S return-local-addr.i return-local-addr.i: In function ‘canonicalize_filename_mode’: cc1: warning: function may return address of local variable [-Wreturn-local-addr] return-local-addr.i:28:25: note: declared here 28 | struct scratch_buffer rname_buffer; | ^~~~~~~~~~~~ This is with GCC 10.2.1 20201125 (Red Hat 10.2.1-9) on x86-64.
