--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Iain D Sandoe <ia...@gcc.gnu.org>: https://gcc.gnu.org/g:716d345c237f030a3e85d7410b06a8c1ac4c46fb commit r10-9539-g716d345c237f030a3e85d7410b06a8c1ac4c46fb Author: Iain Sandoe <i...@sandoe.co.uk> Date: Wed Mar 17 13:05:47 2021 +0000 testsuite, Darwin : Fix the asan/strncpy-overflow-1 test. 1. To be more compatible with Linux, Darwin testcases that include string.h should set _FORTIFY_SOURCE=0 since, otherwise, it will be defaulted on and the _chk versions of the string builtins will be used. This testcase fails otherwise because there's no convenient way to disable the _chk builtins. 2. The system tool that handles symbolization (atos) is not reliable with GCC's DWARF-2 output but, fortunately, all the platform versions that support the current sanitizers are able to handle dwarf-3 for this testcase. gcc/testsuite/ChangeLog: PR sanitizer/96318 * c-c++-common/asan/strncpy-overflow-1.c: Add _FORTIFY_SOURCE=0 and -gdwarf-3 to the command line options. Adjust the expected line numbers for the revised options header. (cherry picked from commit c86c5195c8c02f5891a222f498c074b373aa946c)
