bugs relevant for musl
unreported bugs
+- linux procfs and writev
+
- posix: usage of the cx option in unistd.h
- broken bre support in tre
-
- wchar_t is assumed to be signed in tre (so it is broken on arm)
- broken random in all bsd libc and glibc (bad seed, ub signed int arithmetics)
- search.h implementation bugs in bsd libc and glibc (stack overflow, hsearch crashes on glibc)
- several libm bugs in glibc, fdlibm (freebsd, openbsd, bionic,..)
-
- llvm signal hadnler bug (not async-signal-safe, racy signal masking)
+
- gcc fldpi, fldl2e,.. even with -frounding-math
+
- gcc -fPIC -Os generates GOT for single 32bit consts instead of using immediate value (for float on i386)
+
- llvm signal handler bug (not async-signal-safe, invalid use of c++, racy unmasking) in Support/Unix/Signals.inc
- llvm exit bug (destructor calls exit)
+
- llvm: invalid use of the address of stdin/stdout/stderr in Support/DynamicLibrary.cpp
+
- address sanitizer: various problems: stack detection, include files, ifdef, non-portable code,..
- various c++ projects: depend on constructor order of different tu (gcc 46770)
-
- various c++ projects: NULL in vararg functions without cast to the right pointer type (seen in various gnome projects)
- various projects: assume large thread stack size without setting it up (firefox,..)
- various projects: query the base pointer of the stack to do pointer arithmetics with it (libgc, firefox,...)
- calling dlopen from the constructor of global static object (firefox)
- incorrect usage of feature test macros and configure results (lots of projects)
- usage of obsolete wrong headers (sys/foo.h instead of foo.h and vice-versa, many projects)
- glibc has some missing posix symbols (found by libc-test)
-
-
-
-
-
+
- glibc has broken vfork on mips
+
- glibc integer overflows in time/tz code
+
- linux headers invoke ub by using (1 << 31) eg. MS_NOUSER in inlude/uapi/linux/fs.h
+
- strace: broken handling of vfork
+
- bionic: posix namespace violation, +gratuitous interface breaking
+
- bionic: broken checks in wchar.cpp mbrtowc
+
- gnutls: O_CLOEXEC
+
- arp: posix namespace collision (tm_)
+
- util-linux: cpuset.h __cpumask, etc, sys/ttydefaults.h, __sighandler_t
+
- f() instead of (f)() in configure scripts (or #undef)
+
- bionic/wchar.cpp 'if (n == 0)' is wrong, should be 'if (s == NULL)' and later 'if (n == 0) return -2'
+
- gcc vs c99 annex f issues
+
- gcc dl_iterate_phdr configure check (hard coded solaris header check + glibc/bionic/bsd ifdef + config.host overrides)
+
- libxml2 and glib: ub and several threading and allocation related bugs
