--- Comment #29 from vialav <d...@bk.ru> --- > What about cantor_juliaserver process? I run a watcher, and cantor_juliaserver does never show up, at any stage. Yes, it is present on my system: $ objdump -p $(which cantor_juliaserver) # yields a normal objdump > I had reproduced the issue, in some sense. Well, otherwise an interesting twist, it was, unfortunately, unrelated: I have disabled 'Integrate Plots in Worksheet' checkbox, and re-run Cantor. There was no change in hanging on "Calculation…". May be the starting point(s) would be why cantor_juliaserver does not show up? And what that SIGSEGV upon immediate File->Exit might mean? There was no noticeable change in the backported KDE frameworks 5.58 when they non-backported moved from Qt v5.9.5 to Qt v5.10.0 (mostly only by adding fancy tests, which anyway are unrelated to runtime), so may be it is possible to judge from the gdb output, which the framework might (or might not) need (or does not) my attention. Back to cantor_juliaserver not showing up in the processes: this is what the output shows, when I restart the backend (not too much): wsStatusChange 1 login to julia 1.2.0-rc1 done wsStatusChange 0 interrupting "print(\"Hello world!\")" wsStatusChange 1 wsStatusChange 2 wsStatusChange 1 login to julia 1.2.0-rc1 done wsStatusChange 0 interrupting "print(\"Hello world!\")" wsStatusChange 1 wsStatusChange 2 wsStatusChange 1 login to julia 1.2.0-rc1 done wsStatusChange 2 -- You are receiving this mail because: You are watching all bug changes.
