Ok, this is hilarious. Whether it is a bug or not is an interesting question. The program executed just fine, but the plug-in found a line of text formatted like the compiler formats error output. The plug-in checks compiler and run-time output against a regular expression. This output happened to match and was flagged as an error.

We could tighten up the regular expression now that the compiler is generally better at formatting error output than it used to be. It will leave us missing older errors but that will fade as the user base abandons older compilers. Or, we could detect the compiler version and use different regular expressions per compiler version. There isn’t really a good mechanism to do that implemented at this time.

Would it be possible to only parse for error output if the exit status of the program is non-zero?

[EricBishton]

I'm not sure. It's kinda hard, since the processor is reading and displaying the input stream from the process long before the exit state is known. So that would mean not showing any output until the process is complete, or trying to display, and then later post-process for errors. Either way, it's not how IntelliJ is designed to handle process output.

We will leave this open so we remember to do the research.

It's a shame trace() outputs to STDERR, though I understand why it does. Differentiating between STDOUT and STDERR would be the Unixy way to handle this.
