From da0b9110fc783245aaa88ae6ed28aa6d5fe1bdea Mon Sep 17 00:00:00 2001 From: Ben Kelly Date: Tue, 7 Feb 2017 10:56:47 +0200 Subject: [PATCH] uclibc++: patch bugfix erase() on derived __base_associative When calling erase() on a containers derived from __base_associative (e.g. multimap) and providing a pair of iterators a segfault will occur. Example code to reproduce: typedef std::multimap testmap; testmap t; t.insert(std::pair(1, 1)); t.insert(std::pair(2, 1)); t.insert(std::pair(3, 1)); t.erase(t.begin(), t.end()); Signed-off-by: Ben Kelly --- ...-erase-on-derived-__base_associative.patch | 40 +++++++++++++++++++ 1 file changed, 40 insertions(+) create mode 100644 package/libs/uclibc++/patches/050-Bugfix-erase-on-derived-__base_associative.patch diff --git a/package/libs/uclibc++/patches/050-Bugfix-erase-on-derived-__base_associative.patch b/package/libs/uclibc++/patches/050-Bugfix-erase-on-derived-__base_associative.patch new file mode 100644 index 0000000000..2ddb8a984e --- /dev/null +++ b/package/libs/uclibc++/patches/050-Bugfix-erase-on-derived-__base_associative.patch @@ -0,0 +1,40 @@ +From 946b29e62927eadfc4e87f27b8d30e5974b78c4c Mon Sep 17 00:00:00 2001 +From: Ben Kelly +Date: Mon, 6 Feb 2017 13:08:25 +0200 +Subject: [PATCH] Bugfix erase() on derived __base_associative + +When calling erase() on a containers derived from __base_associative +(e.g. multimap) and providing a pair of iterators a segfault will +occur. + +Example code to reproduce: + + typedef std::multimap testmap; + testmap t; + t.insert(std::pair(1, 1)); + t.insert(std::pair(2, 1)); + t.insert(std::pair(3, 1)); + t.erase(t.begin(), t.end()); + +Signed-off-by: Ben Kelly +--- + include/associative_base | 3 +-- + 1 file changed, 1 insertion(+), 2 deletions(-) + +diff --git a/include/associative_base b/include/associative_base +index 27ae0ef..be8b27f 100644 +--- a/include/associative_base ++++ b/include/associative_base +@@ -200,8 +200,7 @@ public: + } + void erase(iterator first, iterator last){ + while(first != last){ +- backing.erase(first.base_iterator()); +- ++first; ++ first = backing.erase(first.base_iterator()); + } + } + +-- +2.7.4 + -- 2.25.1
