Source: fcoe-utils Severity: important With the most recent upload, the auto-builders detected a build failure on 32-bit architectures that appears to be a regression between gcc-12 and gcc-13. I'm starting the bug report here but will reassign or merge and add an affects once I am able to pin down the root cause or a case that reproduces it outside of fcoe-utils.
Builds on i386, armhf, and armel fail with: > fcoemon.c:1347:9: error: ‘__builtin_strncpy’ output may be truncated copying > between 0 and 15 bytes from a string of length 15 > [-Werror=stringop-truncation] > 1347 | strncpy(msg.ifname, ff->ifname, iflen); > | ^ > cc1: all warnings being treated as errors The same build succeeds on 64-bit architectures, and on 32-bit architectures if you set CC=gcc-12. The only current bug against gcc-13 that looks plausibly related is https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1050589, but it's not clear to me that they are the same.
