Wrote a new feature for our flagship product in C. Worked perfectly, no issues. I was told to wait before submitting to SVN.

Because my company is a little cheap in engineering, they took my Green Hills license for another dev to use. I wasn't using it, and now can't compile.

Then, a month later, I was asked to submit my feature to the repo, they needed it in done version, do I did. Still not able to recompile to see if other changes broke anything...

As you probably guessed, no one's code complied after pulling from the repo! Big embarrassment. Weeks later I was told that it wasn't my fault in the end... I don't remember how my code impacted it, but man, it was a bad day for this dev.

Never again!
