<pre>Does not crash with trunk, so I think this has been fixed. This was the crash
stack trace:
1. <eof> parser at end of file
2. Code generation
3. Running pass 'Function Pass Manager' on module
'/tmp/actor-framework-0.16.0/libcaf_core/test/inspector.cpp'.
4. Running pass 'Merge contiguous icmps into a memcmp' on function
'@_ZN12_GLOBAL__N_19test_implINS_27binary_serialization_policyEEEvRT_'

I see a lot of work on the MergeICmps pass since 7.0, so it's hard to say what
fixed this.</pre>
