request: debug primer

[larry]

I need some basic information.  Because I'm experiencing serious
instability with LyX1.0.3, and I want to report meaningful debug
information to the list.

LyX is sigfaulting often during some reasonably sophisticated work with
tables.  It's a proprietary document, so I can't simply post the content.

Please tell me what software tool I need, and the command line
instruction to run LyX in connection with that tool.

Thank you.
