+Subject: [PATCH] x86-generic/PlatformThread.cpp: avoid non-constant offsetof
+
+On gcc-11 edb-debugger build fails as:
+
+```
+.../x86-generic/PlatformThread.cpp:332:79: error: 'n' is not a constant expression
+ 332 | return ptrace(PTRACE_POKEUSER, tid_, offsetof(struct user, u_debugreg[n]), value);
+ | ^
+```
+
+The change workarounds by avoiding non-constant expression:
