Backtrace from 0.92.x (0670a15bde, 2019-04-22) Linux Mint 19.1
What should have happened?
No crash. This feature is useful as it allows for piping. It is currently not present in 1.0alpha (to my knowledge), so did not test it on 1.0alpha.
Inkscape Version and Operating System:
- 0.92.x (0670a15bde, 2019-04-22) Linux Mint 19.1
- 0.92.3 (2405546, 2018-03-11) Linux Mint 19.1
- 0.47pre4 r22446 Ubuntu 9.10
- 0.46+devel r22653 (Jan 22 2010) Ubuntu 9.10
- ... a lot more, with tests up to 2017 with up to date versions along the way and various OSs (Ubuntu, Debian, Mac)
Alvin Penner:
works normally on Oct 13, 2008, SVN rev 19989
crashes on Nov 20, 2008, SVN rev 20225
Lars Kruse:
The first revision exposing the segfault is rev 20191
From the svn log:
remove old ps exporter, obsoleted by cairo ps export
The relevant diff seems to be the following (but maybe I am wrong) in `src/extension/init.cpp: - Internal::PrintPS::init();`
