+Subject: examples/ucontext-cp.c: cope with variable SIGSTKSZ
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The size of C arrays at file scope must be constant. The following
+compiler error occurs with recent upstream glibc (2.33.9000):
+
+  CC ucontext-cp
+  ucontext-cp.c:31:23: error: variably modified ‘stack_buf’ at file scope
+  31 |         unsigned char stack_buf[SIGSTKSZ];
+     |                       ^~~~~~~~~
+  make[1]: *** [Makefile:26: ucontext-cp] Error 1
+
+The following glibc commit changed SIGSTKSZ from a constant value to a
+variable:
+
+  commit 6c57d320484988e87e446e2e60ce42816bf51d53
+  Author: H.J. Lu <hjl.tools@gmail.com>
+  Date:   Mon Feb 1 11:00:38 2021 -0800
+
+    sysconf: Add _SC_MINSIGSTKSZ/_SC_SIGSTKSZ [BZ #20305]
+  ...
+  +# define SIGSTKSZ sysconf (_SC_SIGSTKSZ)
+
+Allocate the stack buffer explicitly to avoid declaring an array at file
+scope.
