raw2trace ERROR while processing trace collected with -trace_after_instrs and -max_global_trace_refs
Describe the bug I am tracing threadsig.cpp (from https://raw.githubusercontent.com/DynamoRIO/drmemtrace_samples/master/threadsig.x86_64/threadsig.cpp). I am seeing the error shown below while running raw2trace. The failing file is only 10 bytes long.
$ build/clients/bin64/drraw2trace -jobs 1 -indir drmemtrace.threadsig.200629.0229.dir/

Please also answer these questions:
- What happens when you run without any client?
- Not applicable since the issue is with the drcachesim client, but the program runs fine without any client
- What happens when you run with debug build ("-debug" flag to drrun/drconfig/drinject)?
- This was run with debug build. I didn't try the release build.
Expected behavior No error during raw2trace
