Forgotten sourdough dough that smells like pineapples

I'm after a bit of advice, I have some sourdough 'final dough' that I forgot about for a few days on the kitchen bench and now it smells like pineapples - yes pineapples! Only way I can describe it.  My question: is this still safe for consumption? Should I even bother to try and bake it? I live in a sub-tropical climate with indoor temperature around 22 degrees celsius in the kitchen, it seems to be the coolest room in the house, until I start cooking dinner that is.  I must say, I'm not the most successful sourdough baker, my loaves are usually pretty dense in the first place.  I guess forgetting the dough on the kitchen counter doesn't say very much for me I must admit, but you know, sometimes life just happens.  I have been trying to bake sourdough for about six months with limited success but you know how it is.... Anyway, any help or suggestions on whether I should bake would be great, thanks in advance.
