neuralamp LV2 crashes Reaper on Ubuntu Studio 22.04

[guidokon]

Hello ,

i tried to get the neuralamp lv2 to run in Reaper with a fresh install and compile from github on 5.Jan.2024.

After scan the lv2 directory and then try to add the neuralamp lv2 on a track reaper crashes.

from dmesg i read

37.039479] process '/opt/REAPER/reaper' started with executable stack
[ 289.356250] traps: reaper[3000] trap invalid opcode ip:7f7df0c0488b sp:7fff0e0c7ba0 error:0 in neural_amp_modeler.so[7f7df0bfb000+37000]

Ububtu Studio Version

uname -v
#18~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Nov 16 11:27:56 UTC 2

Reaper: version: v7.07

I tried the add to reaper from /usr/lib/lv2 and later after removing it from /usr/lib/lv2 from $HOME/.lv2 and it crashes both times.

In $HOME/.lv2 i changed the owner of all entries to my userid.

I am not sure if i have to set something for rdfs:range atom:Path in neural_amp_modeler.ttl.
Currently its set as i got it from github : rdfs:range atom:Path.

Can you please give some help on it ?

Kind regards
Guido

Do you have an older x86 CPU? If so, see this issue: #52
