With gcc 7.3.0, the build fails like this:
src/xenstat_linux.c: In function ‘getBridge’
src/xenstat_linux.c:78:34: warning: ‘%s’ directive writing up to 255 bytes into a region of size 241 [-Wformat-overflow=]
sprintf(tmp, "/sys/class/net/%s/bridge", de->d_name);
^~
src/xenstat_linux.c:78:5: note: ‘sprintf’ output between 23 and 278 bytes into a destination of size 256
sprintf(tmp, "/sys/class/net/%s/bridge", de->d_name);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Fix by making the buffer bigger.
