Unpredictable behavior of o-code subroutine

Hello,

for my linear tool change I use as M6 remap the attached code with linuxcnc version 2.9.

The exciting thing is that the line G53 G1 Y100 F#29 is stopped in the middle of the movement as soon as I remove the debug output (DEBUG, MSG3) in the next line. What is output there doesn't seem to matter. Neither does it matter that immediately after that a (redundant) G53 G0 Z0 Y100 F#29 follows, which is not executed either.

Do you know problems with subroutines that are terminated too early?

Many greetings
Robert

Hi
DEBUG is a Command
and MSG is also a command
use only one command in one line
so
DEBUG,mymassage
or MSG mymasage

I am a little confused by this description.

Could you perhaps show the version that works and, separately, the version that does not work?
