On Linux systems the stack frame reference canary will be purposely
changed when forking sub-processes (see https://crbug.com/40181003).
To avoid sub-process shutdown crashes the NO_STACK_PROTECTOR
annotation must be added to all functions in the call stack leading to
CefExecuteProcess(). Applications that cannot add this annotation must
instead pass the `--change-stack-guard-on-fork=disable` command-line
flag.
