CFI attempts to verify that the dynamic type of a function object
matches the static type of the function pointer used to call it.
https://clang.llvm.org/docs/ControlFlowIntegrity.html#indirect-function-call-checking
However, the analyzer does not have enough information to check
cross-dso calls. In these instances, CFI crashes upon calling the
function with an error like:
pthread_create_linux.cc:60:16: runtime error:
control flow integrity check for type
'int (unsigned long *, const pthread_attr_t *, void *(*)(void *), void *)'

On Android, the compat library built compat/android/sys/mman.cc, which
provides a fallback for mmap, and compat/linux/sys/mman.cc, which
provides a fallback for memfd_create. This can result in two object
files colliding in the library, which is flagged as a “gn analyze”
error:

The files are renamed to avoid this collision. The associated headers
cannot be renamed because they need to shadow the SDK’s copies. There is
no “gn analyze” conflict reported for headers with the same name.
