--- Comment #1 from David Malcolm <dmalcolm at gcc dot gnu.org> --- Example: https://godbolt.org/z/afvEd99qn #include <stdlib.h> struct s { void *m_a; void *m_b; void *m_c; }; struct s * make_s (size_t sz_a, size_t sz_b, size_t sz_c) { struct s *result = calloc (1, sizeof (struct s)); if (!result) return NULL; result->m_a = malloc (sz_a); if (!result->m_a) goto err; result->m_b = malloc (sz_b); if (!result->m_b) goto err; result->m_b = malloc (sz_c); if (!result->m_c) goto err; return result; err: free (result->m_c); free (result->m_b); free (result->m_a); free (result); return NULL; } void test () { struct s *ptr = make_s (5, 10, 15); /* now leak ptr. */ } This emits 4 -Wanalyzer-malloc-leak warnings with almost identical paths, mostly just varying in the "allocated here" messages.
