Exploding inner tube and track pump

I pumped up my front wheel this evening. I have a fairly cheap track pump and according to the guage the pressure was about 115 psi. About 60 minutes later (and whilst the bike wasn't being ridden) the front inner tube exploded and there is now a 6 inch tear.
I'm assuming I must have pumped up the tyre too much as there was no evidence on the tyre to suggest there was anything sharp which would pop the inner tube. That got me thinking about the track pump and whether the guage might be faulty. Do guages on track pumps go faulty and if so how do you know that when you are putting lets say 120 psi into the inner tube (according to the reading on the guage) that you are in fact putting that amount in and no more and no less?
Are there track pumps that have guages that are always accurate?
Thanks

More likely the tyre wasn't seated properly and slid off, or a duff tube.0

as above, incorrectly seated tyre, or faulty/worn/damaged rim/tyre, most likely the tube was nipped between tyre and rim
to *explode*, a tube has to be outside the tyremy bike - faster than god's and twice as shiny0 -
