 * `1` if the compilation failed.
 * The exit code of the compiled executable otherwise.
 
+Flags specific to `v run`:
+  -use-os-system-to-run
+     Use os.system() to run the produced executable, instead of os.new_process;
+     this is useful as a temporary workaround for segfaults, when running code
+     on macos, that may happen when xcode is updated after 2023/08/30, and for
+     comparing os.system with os.new_process on other systems. Usually used with:
+     `export VFLAGS='-use-os-system-to-run'`.
