--- Comment #2 from Paul Pluzhnikov <ppluzhnikov at google dot com> 2011-09-11 18:17:34 UTC ---
I took a look at a random sample of non-test issues in the report:
---
file="elf/pldd.c" line="198" id="resourceLeak" severity="error" msg="Resource
leak: taskfd"
False positive: cppckeck doesn't understand that fdopendir() transfers
ownership of taskfd to the DIR that is opened.
---
file="nscd/nscd_helper.c" line="186" id="uninitvar" severity="error"
msg="Uninitialized variable: sock"
False positive: cppcheck doesn't understand relationship between SOCK_CLOEXEC
and __ASSUME_SOCK_CLOEXEC.
---
file="posix/regcomp.c" line="2758" id="uninitvar" severity="error"
msg="Uninitialized variable: symb_table"
Probably false positive (but tough to really tell): cppcheck doesn't appear to
understand nested functions.
---
file="stdlib/isomac.c" line="267" id="memleak" severity="error" msg="Memory
leak: command"
True positive, but not very interesting (helper program).
---
file="sysdeps/unix/readdir_r.c" line="113" id="nullPointer" severity="error"
msg="Possible null pointer dereference: dp - otherwise it is redundant to check
if dp is null at line 115"
False positive: cppcheck doesn't understand control flow.
---
file="sysdeps/unix/sysv/linux/opensock.c" line="92" id="uninitvar"
severity="error" msg="Uninitialized variable: result"
False positive (same as nscd/nscd_helper.c).
Bottom line: cppcheck could stand some improvement ;-)
