./hw/xfree86/common/xf86pciBus.c: In function ‘xf86MatchDriverFromFiles’:
./hw/xfree86/common/xf86pciBus.c:1330:52: warning: ‘snprintf’ output may be
truncated before the last format character [-Wformat-truncation=]
snprintf(path_name, sizeof(path_name), "%s/%s", ^~~~~~~
./hw/xfree86/common/xf86pciBus.c:1330:13: note: ‘snprintf’ output between 2
dirent->d_name is 256, so sprintf("%s/%s") into a 256 buffer gives us:
and 257 bytes into a destination of size 256
