 // Writes a microdump (a reduced dump containing only the state of the crashing
 // thread) on the console (logcat on Android). These functions do not malloc nor
 // use libc functions which may. Thus, it can be used in contexts where the
 // state of the heap may be corrupt.
 // Args:
 //   crashing_process: the pid of the crashing process. This must be trusted.
 //   blob: a blob of data from the crashing process. See exception_handler.h
 //   blob_size: the length of |blob| in bytes.
 //   mappings: a list of additional mappings provided by the application.
 //   build_fingerprint: a (optional) C string which determines the OS
 //     build fingerprint (e.g., aosp/occam/mako:5.1.1/LMY47W/1234:eng/dev-keys).
 //   product_info: a (optional) C string which determines the product name and
 //     version (e.g., WebView:42.0.2311.136).
 //
 // Returns true iff successful.
