Release 1.8.16 issue, the attached 7zip (unpacked to c:\ ) appears to repeat the issue with the bcl command line {{burstc @/c/repro/response.log}} from a git bash, using a local release build of release/1.8.16 branch.

Drop the updated response.log into the unpacked directory to reduce the amount of code being compiled. 

The following entry point hash is known to cause a problem : 

e6451c09b175407d87339d3a2266d831 

(got by updating FindEntryPoints just before the return result ) :
{code:java}
result = new HashSet<EntryPointMethod>(result.Skip(21).Take(1).ToArray()); {code}
UNITY_BURST_ENTRY_POINT_METHOD_CHUNK_SIZE=1 was used to ensure one module per entry.
