Run "record-trace" on a plain pinball, not using pinplay crashes, but "run-sniper" does not

[Michael Shires]

Hello,

When I try to run a pinball I generated from SPEC benchmarks using Intel SDE with the "log log:basename" command, it runs fine on "run-sniper", but when I try to pass it to "record-trace" as that's what I'm really interested in, I get this error:

[RECORD-TRACE] Using the SDE frontend (sift/recorder)
[SIFT_RECORDER] sift_writer.cc:117: void Sift::Writer::initResponse(): Assertion `strcmp(m_response_filename, "") != 0' failed.

Does anyone know how to troubleshoot this? It runs fine with "run-sniper". Also is there any documentation for all these python scripts, besides calling them with the "-help" knob? thank you all for your time!
