With my getdelim patch applied, this is the summary of sanitizer findings: $ egrep 'SUMM|checking' config.log|grep -B1 SUMM configure:14038: checking for working C stack overflow detection SUMMARY: UndefinedBehaviorSanitizer: implicit-integer-sign-change conftest.c:379:30 in -- configure:36833: checking whether memmem works SUMMARY: UndefinedBehaviorSanitizer: invalid-null-argument conftest.c:513:32 in -- configure:55268: checking whether fchownat works with AT_SYMLINK_NOFOLLOW SUMMARY: UndefinedBehaviorSanitizer: implicit-integer-sign-change conftest.c:812:50 in configure:55326: checking whether fchownat works with an empty file name SUMMARY: UndefinedBehaviorSanitizer: implicit-integer-sign-change conftest.c:817:37 in -- configure:67322: checking whether glob lists broken symlinks SUMMARY: AddressSanitizer: 37 byte(s) leaked in 2 allocation(s). -- configure:94107: checking for working re_compile_pattern SUMMARY: AddressSanitizer: 20072 byte(s) leaked in 116 allocation(s). The lzip'ed tar archive with all 4 files is 137k. Is it ok to send it here or do you better like via PM ? Regards, Tim
