Description Tor Lillqvist 2017-09-25 14:19:58 UTC
Noticeable at least at a7ce8404befaf59df5f1a476c8dd414633bbf823 . (Will check whether possibly has gone away since.)

Will attach a zip archive with reproduction executable.

- Build LO with debugging symbols

- Start it, instdir/program/soffice

- Attach it in VS

- In another Cygwin shell, go to where this zip is unpacked and run:
  THISDIR='c:/where/ever/this/is/' ./BugReproducer.exe

After the "Closing document" you will see the abort() hit in VS.

Steps to Reproduce:

Actual Results:  

Expected Results:

Reproducible: Always

User Profile Reset: No

I just get a "Open calc /srv/dev/COM-bug/BugReproducer.xls", but nothing else happens. I also tried starting LO with "make debugrun" - no change.

THISDIR="$(pwd)/" ./BugReproducer.exe
Comment 3 Tor Lillqvist 2017-09-25 18:45:07 UTC
I don't think $(pwd) will work as is a Cygwin-format pathname? (Hmm, or does Cygwin automatically translate it to Windows format before exporting to the Windows process?)

I guess one possibllity is that some Registry magic is not present on that machine; have you even installed LO from an installer on it? I am not entirely sure how the COM stuff works. But presumably some magic in the Registry takes care of the fact that the source code of the program contains only "com.sun.star.ServiceManager" and somehow that is supposed to make it contact the running soffice.bin.
Comment 4 Jan-Marek Glogowski 2017-09-26 11:50:00 UTC
To get a Windows patch, the correct call is actually 

THISDIR="$(cygpath -w -a -l $(pwd))\\" ./BugReproducer.exe
