[LV2] ardour3 plug-in analysis

[hermann meyer]

Hi

I have a question to ardour3's plug-in analysis, didn't know if I'm 
right here, but as far I know, Dave you have wrote it, didn't you?

So, my question is, what did the analysis do, or in which files could I 
found the source.
I still working on the GxAmplifiers, and I notice that ardour3 will 
crash with a segfault, when I try to use the plugin analysis from the 
internal plug-in UI.
I nail it down to the convolver implementation, the analysis work fine 
when the convlovers are disabled.
But right now I have no idea why the analysis crashed when the 
convolvers be enabled.
I have already set the convolvers to don't use variable block-size.
The plugs work well otherwise in ardour3, qtractor and jalv.

the implementation of the convolvers is here:

any hint how I could solve that will be welcome
