Summary0007970: Some of the U-he linuxVST plugins segfaults
DescriptionTrying out Ardour-6.0.pre1.78 and Ardour-6.0.pre1.92 nightly builds quickly

Some U-he plugin segfaults Ardour instead of showing their native Gui

Seg faults:
ZebraHZ-9724, Repro1-9669, Repro5-9669
(Repro1 and Repro5 is technically the same linvst binary)

Works ok:
Diva-9775, ColourCopy-9775,Hive-9775,Presswerk-9775,Zebra2-9775,Satin-9775,

the seg faulting linVSTs above works fine in Carla on the same machine


Ubuntu studio 19.10 on a Intel PC (Thinkpad T540p) kernel
Steps To ReproduceTry the (at the time of writing) latest U-he plugins and some will not load the gui but kill Ardour

The same behavior seems to happen under Ardour 5.12 (Ubuntu Studio package) on the same machine so it doesn't seem to be any worse than in 5.12
Maybe this is an Ubuntu Studio issue..
Additional InformationThis is what dmesg shows that seems related to the problem..

This needs to be reported to U-he. But before doing so, I would advise getting a full backtrace from gdb, as described here: http://ardour.org/debugging_ardour

Since this is a U-he problem, it should be reported to U-he
