Tested a bunch of issues regarding Fedora 28/29. I think this issue should be closed. Gotta make sure _FORTIFY_SOURCE=2 was enabled in at least some of my tests. I'm not sure how to ensure _FORTIFY_SOURCE=2 is enabled in 1.0alpha/0.92.x I have tested on a build in a Fedora 28 VM for both of them and they show no error. Tested on a Release build, which has -D_FORTIFY_SOURCE=2 and -O2 set, but I don't know how to ensure/test that these flags aren't overridden. I've attached the contents of compile_commands.json (generated by cmake I think) ====== "Method" Here are the builds I've tested with 1. dnf install inkscape now installs inkscape 0.92.4 (unknown) on Fedora 28 2. dnf install inkscape now installs inkscape 0.92.4 (unknown) on Fedora 29 3. 1.0alpha 2019-04-16 (d7d7b926b4) custom build set to Release on Fedora 28 4. 0.92.4 2019-03-29 (da74ff7714) custom build set to Release on Fedora 28 5. dnf install inkscape && dnf downgrade inkscape to 0.92.2 (5c3e80d 2017-08-06) on Fedora 28 6. Last minute 1.0alpha appimage Fedora 29 from inkscape.org (i.e. not a job artefact) Here are the issues I've tested: a. This one (https://bugs.launchpad.net/inkscape/+bug/1768958), namely: a1. Newline on new text a2. create some text then hit enter a3. edit some text (try to check two positions, see https://bugzilla.redhat.com/show_bug.cgi?id=1575842#c24) a4. loading file with line break in normal text b. two files in https://bugs.launchpad.net/inkscape/+bug/1769662 c. open Faust.svg mentioned in comments of https://bugs.launchpad.net/inkscape/+bug/1769394 d. pasting text with newline https://bugzilla.redhat.com/show_bug.cgi?id=1575842#c9 e. navigating up and down with text (single newline) https://bugzilla.redhat.com/show_bug.cgi?id=1575842#c21 f. highlighting text https://bugzilla.redhat.com/show_bug.cgi?id=1612618#c3 g. problem mentioned in https://bugs.launchpad.net/inkscape/+bug/1788977 (see video they uploaded with double click of A) h. Open file mentioned in https://bugs.launchpad.net/inkscape/+bug/1774888 i. Double click single char in flowtext. https://bugs.launchpad.net/inkscape/+bug/1773050 j. https://bugs.launchpad.net/inkscape/+bug/1779779 (note marked fix released already but testing anyway) k. https://bugs.launchpad.net/inkscape/+bug/1773049 (unclear instructions) ===== Results 1, 2, 3, 4, 6 have no relates crashes or error messages. There were some crashes in 4, and some errors when opening 6. but unrelated to this. 5. For the 0.92.2 build: a4 possibly replicated (I created the line break inbetwee two other lines) but then crash if file had an empty tspan `` (i.e. empty line) b. crash on open for first file (unexpected, prevents replication) and crash with other file (replication). I removed an empty tspan from the first file but I couldn't replicate the problem. If they tried adding a newline, then yes, I did replicate (crash on adding a newline). f. crash when highlighting to the end of the line j. not really replicated. PgDn from somewhere else (and thus ending on the last line) does crash it but not when the cursor is already at the end. k. replicated? Unclear instructions rest were replicated unremarkably. ==== Extra notes: Tavmjong replicated on stock Inkscape (0.92.3 at the time) but not 0.92.x build in Fedora 28 (for https://bugs.launchpad.net/inkscape/+bug/1769662). I'm not sure if _FORTIFY_SOURCE=2 was enabled. Is it worth asking (this was nearly a year ago!) Problem was replicated in Fedora 29 too, but again in 0.92.3-5.fc29 (https://bugzilla.redhat.com/show_bug.cgi?id=1575842#c28) Fix mentioned regarding an exception for Layout_TNG_OutIter.cpp but I can't see it in the 0.92.x branch (which I can't replicate problems with), so probably unrelated Most of these bugs have not been mentioned after 0.92.4 was released (2019 onwards), but this could just be because the issues are old (problem was replicated in November in comments 2 and 3 https://bugzilla.redhat.com/show_bug.cgi?id=1612618) No wait: https://bugs.launchpad.net/inkscape/+bug/1779779/comments/2 and https://bugs.launchpad.net/inkscape/+bug/1779779/comments/3 both confirm Inkscape 0.92.4 from dnf on Fedora 29 have no error (at least for that issue). ==== Conclusion Nearly all issues were replicated in 0.92.2. All were at least partially replicated, if following the instructions "in spirit". None of them were replicated in 0.92.4 or 1.0alpha in Fedora 28 or Fedora 29. Thus I recommend closing them as they are no longer issues. https://bugs.launchpad.net/inkscape/+bug/1769394 https://bugs.launchpad.net/inkscape/+bug/1788977 https://bugs.launchpad.net/inkscape/+bug/1774888 https://bugs.launchpad.net/inkscape/+bug/1773050 This had unclear instructions but I still think should be closed: k. https://bugs.launchpad.net/inkscape/+bug/1773049 These may not have been followed correctly but should probably still be closed: https://bugs.launchpad.net/inkscape/+bug/1769662 only https://bugs.launchpad.net/inkscape/+bug/1768958/comments/5 was not replicated in some cases (ambiguous)
