Two days down the drain...

I just wasted two days trying to restore my eclipse environment.

Late Friday afternoon, out of the blue, the eclipse IDE on my Mac OSX laptop no longer was able to run the debugger. I kept receiving the follow error:

Invalid memory access of location 0x14 rip=0x1007f6d22

After much fruitless searching and dead end attempts to fix it, I decided to reinstall the OS. No luck, still broken - but after a second install, I got a different error message that pointed to the problem: During the updating of my hosts file, I had accidentally blown away my localhost definition. After I restored the defintion, voila - problem solved!
