I haven't had an LED explode, but I've had two (out of maybe 60+) CFLs blow. With that said, I'm pretty sure the fire risk was less than when an incandescent malfunctions/blows, since those are much higher wattage.

Eventually the pressure builds so much that the LED explodes. But...what exactly gets changed to gas?

I tried googling this, but it seems the internet is more interested in making LEDs (and caps) explode than explaining why they do so.
YMMV, but my first result is this...

Which suggests it's the electrolyte that's vaporized. If the cap doesn't pop as designed to relieve the pressure, enough pressure can build up to put a whole in something when it blows off.

Had older filament types shatter, got plenty of LED's but none exploding.
