Dominique can I ask you two questions: > > 1) I'm not good in Darwin, do you use relatively new distro? If you speak of MacOSX, I see the problem since I have updated to « El Capitan » (darwin-15) and the tool chain is Xcode 7.2. That is what I use for both gcc 5 and trunk and I am using recent revisions (less than a day, r232227 for gcc5) of GCC. > If so, this may > explain why you don't observe test failures on trunk (because on new distros > dynamic linker doesn't require DYLD_INSERT_LIBRARIES to be set). > > 2) Could you run memcmp-1.exe with > ASAN_OPTIONS=allow_reexec=0:debug=1:verbosity=2 > > setenv ASAN_OPTIONS verbosity=2:debug=1:allow_reexec=0 The test succeeds with this env. Note that asan is broken on the gcc 5 branch not only in the test suite, but also for « real » use: [Book15] f90/bug% gfc5 pr60795.f90 -fsanitize=address [Book15] f90/bug% a.out ==93807==AddressSanitizer CHECK failed: ../../../../5_work/libsanitizer/asan/asan_malloc_mac.cc:103 "((!asan_init_is_running)) != (0)" (0x0, 0x0) <empty stack> [Book15] f90/bug% setenv ASAN_OPTIONS allow_reexec=0 [Book15] f90/bug% a.out 10 1 Dominque
