RNG is expected to provide the same values, but if e.g. the code is compiled slightly differently because 
the system headers are different, then the coverage feedback will be different and hence the RNG will be called in different order.

This is very strange. 
I've just ran the test manually for a few times with different seeds and it always finds the bug quickly.

  clang -g -std=c++11 -fsanitize=address,fuzzer ~/llvm/projects/compiler-rt/test/fuzzer/ShrinkControlFlowSimpleTest.cpp
  ./a.out -exit_on_item=0eb8e4ed029b774d80f2b66408203801cb982a60 -runs=1000000 -jobs=100
