+Subject: [PATCH] Bug 435441 - Handle weak symbols as global for redirection
+
+Weak symbols are global but with lower precedence, so they should
+be handled the same way as global symbols during malloc replacement.
+
+This fixes valgrind on musl 1.2.2 when it is not patched with a
+soname (as is done on Alpine Linux).

+commit e04914e10126d3a8de13302e958bbfd5e83a6637
+Author: Romain Geissler <romain.geissler@amadeus.com>
+Date:   Mon Jan 30 16:09:47 2023 +0000
+
+    Fragile temporary fix for https://bugs.kde.org/show_bug.cgi?id=464671: avoid using @GLIBC_VERSION@ with our recent toolchains.
+    
+    This is fragile as it might a bit too many things (especially ld*.so, which maybe shall be written "ld-linux-*.so" to be a bit more robust)
+    and also it doesn't work for glibc < 2.34.
+    
+    Ideally something similar to GLIBC_LIBC_PATH shall be introduced for ld.so and libdl.so, so that
+    it covers both glibc < 2.34 and glibc >= 2.34.

+		Valgrind is a GPL'd tool to help you find memory-management problems
+		in your programs. When a program is run under Valgrind's supervision,
+		all reads and writes of memory are checked, and calls to
+		malloc/new/free/delete are intercepted. As a result, Valgrind can
+		detect problems such as
+
+		- Use of uninitialised memory
+		- Reading/writing memory after it has been free'd
+		- Reading/writing off the end of malloc'd blocks
+		- Reading/writing inappropriate areas on the stack
+		- Memory leaks -- where pointers to malloc'd blocks are lost forever
+		- Passing of uninitialised and/or unaddressible memory to system calls
+		- Mismatched use of malloc/new/new [] vs free/delete/delete []
+		- Some abuses of the POSIX Pthreads API
