Neat! Hadn't come across this tool before but it let me track down a PulseAudio crash that's been bugging me for months. Turns out that it was unloading a shared library whilst executing code from that shared library, which meant that the inevitable crash happened in code that was no longer loaded, and that was why I couldn't get a meaningful backtrace at the time of the crash. The call to dlclose() right before the crash was a huge hint; knowing that was the last library function called made it easy to set a breakpoint and catch it in the act. Thanks for the tip!
