+Subject: [PATCH] cmake: Fix C compatibility of libunwind probes
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Future compilers such as GCC 14 are likely to enforce C type
+compatibility rules by default and report errors like this one:
+
+…/TryCompile-aAxUZn/src.c: In function ‘main’:
+…/TryCompile-aAxUZn/src.c:3:43: error: passing argument 1 of ‘unw_backtrace’ from incompatible pointer type
+    3 | int main() { void* buf[10]; unw_backtrace(&buf, 10); return 0; }
+      |                                           ^~~~

+      |                                           void * (*)[10]
+In file included from /usr/include/libunwind-x86_64.h:129,
+                 from /usr/include/libunwind.h:23,
+                 from …/TryCompile-aAxUZn/src.c:2:
+/usr/include/libunwind-common.h:318:27: note: expected ‘void **’ but argument is of type ‘void * (*)[10]’
+  318 | extern int unw_backtrace (void **, int);
+      |                           ^~~~~~~
+
+Removing the address operator ensures that the array type decays to
+a pointer, and that the types are compatible.
