--- Comment #8 from AL <l...@ncbi.nlm.nih.gov> --- > $ gcc -O2 -Wall -g -o vbug vbug.c > vbug.c: In function ‘main’: > vbug.c:10:5: warning: ‘strncat’ accessing between 1 and 9223372036854775805 > bytes at offsets [0, 9223372036854775805] and 0 may overlap 1 byte at offset > [0, 9223372036854775807] [-Wrestrict] Starting with some later versions, GCC have gone to some great extreme with both their warnings and the usefulness of such, which is borderline absurdish, at times -- just try to take a look at the bounds above... > An implementation might copy 8 bytes at a time if len == 7 Okay, let's say this is the case, then the code still works correctly, overwriting the ending '\0' byte in dst (which also happens to be shared with src) -- but that's what was going to happen, anyways. -- You are receiving this mail because: You are watching all bug changes.
