Bug#833563: libfuzzer-3.8-dev: illegal hardware instruction

[Chris Lamb]

Package: libfuzzer-3.8-dev
Version: 1:3.8.1-7
Severity: normal

Hi,

First, thanks for packaging libFuzzer! Unfortunately, I'm getting
the following:

$ apt-get install libfuzzer-3.8-dev clang-4.0
[..]

$ cat << EOF > test_fuzzer.cc
#include <stdint.h>
#include <stddef.h>
extern "C" int LLVMFuzzerTestOneInput(const uint8_t *data, size_t size) {
  if (size > 0 && data[0] == 'H')
    if (size > 1 && data[1] == 'I')
       if (size > 2 && data[2] == '!')
       __builtin_trap();
  return 0;
}
EOF

$ clang++-4.0 -fsanitize=address -fsanitize-coverage=edge test_fuzzer.cc /usr/lib/llvm-3.8/lib/libFuzzer.a

zsh: illegal hardware instruction  ./a.out

$ echo $?
132

Any ideas?
