// When using cgo, call the C library for mmap, so that we call into

// sanitizer with Go programs. The memory sanitizer only applies to

// C/C++ code; this permits that code to see the Go code as normal

// program addresses that have been initialized.

// To support interceptors that look for both mmap and munmap,

// also call the C library for munmap.
