+Subject: [PATCH 1/1] Fix segfault with musl libc
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+shairport-sync crashes on musl libc when accessing the `statistics` array in
+`player_thread_func()`. This array is quite large (60128 bytes) and the data
+for this thread exceed the the default stack size on musl libc of 80k [1].
+
+Safe and portable programs should not depend upon the default stack limit, but
+instead, explicitly allocate enough stack for each thread by using the
+pthread_attr_setstacksize routine [2].
+
+So, lets set the stack size for the `player_thread` to 128k. A follow-up patch
+may set the stack sizes for the other threads, too. The difficulty here is to
+decide how much memory to allocate for the stack.

+Subject: [PATCH 2/2] Fix redirection of incorrect system headers
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The POSIX correct header include is `<poll.h>` [1] and `<signal.h>`
+
+The glibc silently redirects these incorrect includes, musl libc prints
+a warning:
+ #warning redirecting incorrect #include <sys/poll.h> to <poll.h>
+ #warning redirecting incorrect #include <sys/signal.h> to <signal.h>
