+Subject: [PATCH] [sanitizer] Remove rsp from the clobber list in
+ internal_clone
+
+Summary:
+When compiling with WERROR=ON, a new fatal warning started popping up recently
+(due to -Werror,-Winline-asm):
+```
+.../lib/sanitizer_common/sanitizer_linux.cc:1214:24: error: inline asm clobber list contains reserved registers: RSP [-Werror,-Winline-asm]
+                       "syscall\n"
+                       ^
+<inline asm>:1:1: note: instantiated into assembly here
+        syscall
+^
+.../lib/sanitizer_common/sanitizer_linux.cc:1214:24: note: Reserved registers on the clobber list may not be preserved across the asm statement, and clobbering them may lead to undefined behaviour.
+                       "syscall\n"
+                       ^
+<inline asm>:1:1: note: instantiated into assembly here
+        syscall
+^
+```
+
+Removing `rsp` from the clobber list makes the warning go away, and does not
+appear to have a functional impact. If there is another way to solve this, let
+me know.
