Bug ID: 15374
Summary: False positive on strsep function call
Product: clang
Version: trunk
Hardware: PC
OS: FreeBSD
Status: NEW
Severity: enhancement
Priority: P
Component: Static Analyzer
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
We implement the following use case of strsep() function:
char *my_function(const char *conf)
{
char *cert, *ca;
if (conf == NULL)
return NULL;
cert = strdup(conf);
if (cert == NULL)
return NULL;
ca = strsep(&cert, g_sep);
6 ← Memory is never released; potential leak of memory pointed to by 'cert'
if (cert == NULL)
{
free(ca);
return NULL;
}
...
free(ca);
return (cert);
}
We have a false positive alert after the call of strsep(). The memory pointed
by cert (which is pointed also by ca) is well-released.
