There were a lot of changes in NppExec during this month, and I believe now the plugin is in a release candidate state.
The built-in RegExp-based filter for compiler error messages is disabled by default to avoid an impact on performance.
It is recommended to enable this filter locally, right before running a compiler or an interpreter: "npe_console local -- x+".

Do you have any changes to the regular expressions used by this filter?

By the way, I've made some performance tests to understand why the all-in-one compilation script (that you initially created) requires noticeable time to be executed.
The short answer is: use npe_console - to disable the output and to make it very fast.
The longer answer is: the CScriptEngine itself is fast enough, but the Rich Edit control (responsible for all the text in NppExec's Console) is sooooo slooooooow...
Here is a simple example. Consider the following NppExec's script:

npp_console ?
npp_console -
npe_console local m+
:1
goto 1

If you execute it as is, it is lightning-fast, it shows "GOTO was performed more than 10000 times" almost immediately. This is the performance of the CScriptEngine itself.

Now, let's close NppExec's Console and modify this script:

npp_console ?
//npp_console -
npe_console local m+
:1
goto 1

This second version prints "GOTO: 1" to a hidden RichEdit window 10000 times. You might think that a hidden RichEdit window should not take much time to repaint itself while adding these lines, but in reality this version takes much longer than the previous one! This is the performance of the CScriptEngine plus Rich Edit control.

I also did some profiling using Visual Studio - and most of the time is indeed spent within the Rich Edit control!
Here is the profiling statistics:
