break does change the exit code on SIGINT

[andry81]

Tests:

https://github.com/andry81/contools--debug/tree/HEAD/test_error_level_for_break_after_sigint.bat

@echo off

setlocal

rem requires CTRL+C or CTRL+BREAK because of infinite loop, but does not print `^C` because `break` sets ERRORLEVEL=255 on SIGINT
cmd.exe /c @for /L %%i in () do @break & call :ERR_FILTER

echo ERRORLEVEL=%ERRORLEVEL%

exit /b

rem DOES skip `Terminate Batch Job`
:ERR_FILTER
exit /b

Result:

ERRORLEVEL=255

Note

This issue happens additionally to the exit code reset after cmd.exe start: #45

Note

The break in the cmd.exe command line still can change the exit code: #46
