Think I found the issue:
If I uninstall lsp-plugins.lv2 (1.2.17) ardour starting normal.
lsp-plugins-vst, lsp-plugins-vst3 working.
Crash happens since Ardour 8.6.518.
Ardour 8.6.511 working.

I see the same issue here with a self compiled copy of ardour-8.6.523.
Other than in @axras case removing lsp-plugins does not "solve" this issue. Even hiding the .lv2-folder in the user home had no effect.
The crashing only stops when i additionally hide the /usr/lib/lv2 folder which contains quite some entries.

It looks like some lv2 plugins (lsp + n) do cause severe problems with the recent changes in ardour. It could be somewhat cumbersome to pin point which exactly those are.

Tell me if you want some additional information like backtraces (they are very much the same here as the one originally posted).

Seems that the recent 3 LV2 commits from Sep. 7 causing the crash.

Thank you. That backtrace was very helpful.

Fixed in 8.6-524-gc0b61d5a28 , those plugins should now work again.

Can confirm it is working here again. Thanks.

FYI, those other plugins triggering this issue on my machine were calf.lv2 and Surge.lv2

@x42 Looking at the clause following, which also initializes `LilvNode* name = lilv_port_get_name(p, port);`, it seems as though [this change](https://github.com/Ardour/ardour/commit/c0b61d5a2856b215761911da0e7569658ed52154#diff-0ca680558736cf8ddbfa7b7cd9a03dbe9586bcb91cf2fe758b542fb0de1bcff9L3987) should also include `lilv_node_free(name);` after the bit which uses `name`.

Or else promote the initialization to the top of the loop and the cleanup to the end (I don't know how performance sensitive this bit of code might be). I tried to include a screenshot but it was too big for Mantis.
