(1)经过查看相关类似issue,得出stringop-truncation选项导致,由于当前vsftpd中编译选项存在"-Werror"选项,会将stringop-truncation的报错当做error退出。 (2)经过回退gcc代码,回退到12.30增加补丁之前的版本,vsftpd编译成功。 (3)应该于bf16-and-matrix-characteristic.patch补丁相关。 3、结论: gcc确认关于stringop-trunca...
I tested your patch and it works, no compiler warnings in same setup as above (gcc-9.3.0).Strncpyalways doing the null termination, seems to make the GCC stringop-truncation heuristics happy. Locally, I had also tried this patch, which works, but I prefer yours. ...
