--- Comment #10 from prathamesh3492 at gcc dot gnu.org --- On a related note, Jim told me he is seeing following failures on aarch64-none-elf before and after updating the tree. FAIL: gcc.c-torture/execute/builtins/memset-chk.c execution, -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects FAIL: gcc.c-torture/execute/builtins/snprintf-chk.c execution, -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects FAIL: gcc.c-torture/execute/builtins/vsnprintf-chk.c execution, -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects However he isn't seeing the failure for strcat-chk.c before or after. Before he updated the tree, it was older than 23rd Nov, which didn't contain r242745. Perhaps the issue is sth else ? Bin, are you able to see the above test-cases FAIL too ? Thanks, Prathamesh
