SIGQUIT gives you a core dump which you can peruse / scrape at your leisure. This is funny because normally I consider core dumps to be a barbaric relic of the card deck days. Core dumps are literally a shadow of what was going on so you have to guess. In the mid 70s I was debugging crashed processes by attaching to them with all network connections, files etc all open so I could frob them and figure out what was going. Then again, ITS used the a debugger as its "shell" so was ultra hacker friendly. This should still be the default, but most POSIX systems can't even support it.
