File with embedded macro

Open attached document. It contains a macro. Open Basic IDE and go to that macro.
Set the cursor at the start of a line, e.g. at start of line#14. Press Enter key. LibreOffice crashes.

Same in LO 5.4 does not crash.

On pc Debian x86-64 with master sources updated today, I could reproduce this.

Indeed when reverting the quoted commit, I don't reproduce the crash.

I submitted this patch to review on gerrit:

Thank you Raal for having pinpointed the faulty commit and having pinged me! :-)
