From f8cef4d07d9641e27629bd3ce2d13f5d702fb251 Mon Sep 17 00:00:00 2001 From: DJ Delorie Date: Wed, 19 Jul 2017 13:14:34 -0400 Subject: [PATCH] Fix cast-after-dereference Original code was dereferencing a char*, then casting the value to size_t. Should cast the pointer to size_t* then deference. --- ChangeLog | 4 ++++ grp/grp-merge.c | 2 +- 2 files changed, 5 insertions(+), 1 deletion(-) diff --git a/grp/grp-merge.c b/grp/grp-merge.c index 6590e5d..035e7a6 100644 --- a/grp/grp-merge.c +++ b/grp/grp-merge.c @@ -137,7 +137,7 @@ __merge_grp (struct group *savedgrp, char *savedbuf, char *savedend, /* Get the count of group members from the last sizeof (size_t) bytes in the mergegrp buffer. */ - savedmemcount = (size_t) *(savedend - sizeof (size_t)); + savedmemcount = *(size_t *) (savedend - sizeof (size_t)); /* Get the count of new members to add. */ for (memcount = 0; mergegrp->gr_mem[memcount]; memcount++) -- 1.8.3.1
