#1666 tools+ output window is blank/crashes while running a command

[Terry Pascar]

tested in rev 14050 on Windows 11
more specifically, stdout and stderr based commands do not echo in the tools output window after execution (or outright crash the entire application).
for testing (Windows):

1. download the attached zip archive and then extract its contents
2. open code::blocks
3. import the attached tool file (Tools+ -> enter the dialog -> Import... -> select the tool file "test" -> click OK to save and close the changes)
4. create and open an empty project (or use the included project in the archive)
5. click on Tools+ and then click on the tool "test"
6. enjoy the fireworks
