Subject: is musl run against cppcheck ?
Hello Everyone,
I was just looking at musl to help with static compiled binaries for
systems that use CF cards for the base OS, I always run code against
cppcheck prior to use so that up front I know what may have to explain
to someone.
In running against an older version of cppcheck, my main system is
being rebuilt and the backup hasnt been upgraded yet, I ran across the
following
[src/network/getaddrinfo.c:115]: (error) Null pointer dereference
[src/network/if_nameindex.c:52]: (error) Memory leak: p
[src/thread/sem_open.c:45]: (error) Possible null pointer dereference:
semtab - otherwise it is redundant to check if seis null at line 45
My coding experience is spotty and I know cppcheck can throw false
positives so instead of guessing I wanted to see if the musl code had
been run through cppcheck.
I ran the below but just filtered out some of the possible/probably
false positives, though the ones referring to ccosh.c might be real.
/musl# script -c "/root/cppcheck --force --enable=all ."
cppcheck-output-musl.txt
Thanks,
Roger
