I think is an issue with GCC's buffer overflow analysis accuracy Found an issue for it, on GCC v12.4, I am using v13.3
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114374 I have found quite a lot of issues relating to this on StackOverflow and elsewhere but no reference to it on the GCC mailing list. Hoping this might be fixed soon, it might reduce quite a lot of noise. https://github.com/AaronNGray/pdfalto/actions/runs/13463238846/job/37623204502#step:9:450 ``` /home/runner/work/pdfalto/pdfalto/src/AnnotsXrce.cc:444:59: warning: ‘%lg’ directive output may be truncated writing between 1 and 13 bytes into a region of size 8 [-Wformat-truncation=] 450 444 | snprintf(temp, sizeof(temp), "%lg", x); 451 | ^~~ 452/home/runner/work/pdfalto/pdfalto/src/AnnotsXrce.cc:444:58: note: assuming directive output of 12 bytes 453 444 | snprintf(temp, sizeof(temp), "%lg", x); 454 | ^~~~~ ``` ``` snprintf(temp, sizeof(temp), "%lg", x); ``` https://github.com/AaronNGray/pdfalto/blob/buffer-overflows/src/AnnotsXrce.cc#L444 ``` char *temp = (char *) malloc(16 * sizeof(char)); ``` https://github.com/AaronNGray/pdfalto/blob/buffer-overflows/src/AnnotsXrce.cc#L419 -- Aaron Gray Independent Open Source Software Engineer, Computer Language Researcher, Information Theorist, and amateur computer scientist.
